We got the same message from that number. He said he was a lawyer from the same office. He had information on a friend of mine and said I was implicated in the case and that a warrant was being issued in the morning.

Guy said his name was Detective Green said a friend of mine was gonna have 2 felony warrants out for her arrest if he wasn't contacted by today. Asked me who he was speaking with. I would think that you already should know who you're calling if you gave out this much info but when I started asking questions he didn't want to tell me his first name or what it was pertaining to....

The Federal Trade Commission (FTC), the nation's consumer protection agency, is warning consumers to be on the alert for scam artists posing as debt collectors. It may be hard to tell the difference between a legitimate debt collector and a fake one. Sometimes a fake collector may even have some of your personal information, like a bank account number. A caller may be a fake debt collector if he:

•is seeking payment on a debt for a loan you do not recognize;
•refuses to give you a mailing address or phone number;
•asks you for personal financial or sensitive information; or
•exerts high pressure to try to scare you into paying, such as threatening to have you arrested or to report you to a law enforcement agency.

If you think that a caller may be a fake debt collector:

•Ask the caller for his name, company, street address, and telephone number. Tell the caller that you refuse to discuss any debt until you get a written "validation notice." The notice must include the amount of the debt, the name of the creditor you owe, and your rights under the federal Fair Debt Collection Practices Act.
If a caller refuses to give you all of this information, do not pay! Paying a fake debt collector will not always make them go away. They may make up another debt to try to get more money from you.•Stop speaking with the caller. If you have the caller's address, send a letter demanding that the caller stop contacting you, and keep a copy for your files. By law, real debt collectors must stop calling you if you ask them to in writing.
•Do not give the caller personal financial or other sensitive information. Never give out or confirm personal financial or other sensitive information like your bank account, credit card, or Social Security number unless you know whom you're dealing with. Scam artists, like fake debt collectors, can use your information to commit identity theft – charging your existing credit cards, opening new credit card, checking, or savings accounts, writing fraudulent checks, or taking out loans in your name.
•Contact your creditor. If the debt is legitimate – but you think the collector may not be – contact your creditor about the calls. Share the information you have about the suspicious calls and find out who, if anyone, the creditor has authorized to collect the debt.
•Report the call. Contact the FTC and your state Attorney General's office with information about suspicious callers. Many states have their own debt collection laws in addition to the federal FDCPA. Your Attorney General's office can help you determine your rights under your state's law.

Although this number has a San Antonio area code and prefix (210-399-xxxx) it appears to actually be from a person or persons working on behalf of a collection agency out of Illinois. A bogus name is given at first; i.e John Green, Tony Rich, John Levin among others, however, the number is associated with a Mr. Ray Buchanan. He uses "strong arm" tactics in his practices that include revealing personal information to outside third parties, impersonating law enforcement officers, threats of imprisonment and arrest and other violations of the FAIR DEBT COLLECTION PRACTICES ACT (FDCPA). Further research seems to indicate Mr. Buchanan works as a collections' agent for PN Financial (& Associates) out of Illinois. The principals of PN Financial are ... 1)  Nelson Macwan (President), 2) Frank Grossman , 3) John Sullivan, 4) Greg Swider. They list multiple locations and phone numbers out of Illinois.This is what I have found out about PN Financial:

On January 11, 2012, Illinois Attorney General Lisa Madigan announced a suit against P.N. Financial Inc. and Nelson Macwan, individually and as President of P.N. Financial Inc. (hereafter Defendants) for violations of the Illinois Consumer Fraud and Deceptive Business Practices Act, the Illinois Collection Agency Act, and the federal Fair Credit Reporting Act.

Madigan alleges the Defendants revealed information about a debt to a third party, impersonated an attorney and failed to reveal their true identity as a debt collector, and made threats about false lawsuits. In addition, the lawsuit purports the Defendants made false threats of seizure, garnishment, attachment, or sale of property or wages. Furthermore, Madigan claims the defendants harassed consumers about a debt at their workplace and revealed information about the debt to co-workers. Additionally, Madigan alleges the Defendants used abusive or profane language, made unauthorized withdrawals of money, failed to send first notice of debt, and misrepresented the nature of the debt. The lawsuit also reports that the Defendants disclosed social security numbers, abused access to credit reports, and made unauthorized collection of debts.

Madigan asks the court to prohibit the defendants from violating the Consumer Fraud Act and the Collection Agency Act. Additionally, Madigan requests the court to declare that all contracts entered into  Consumer Financial Protection Bureaubetween the Defendants and Illinois consumers by the use of methods and practices are unlawful and rescinded and required that full restitution be made to said consumers. Madigan also requests that the Defendants be permanently enjoined from engaging in the impermissible use and obtaining of consumer credit reports. Furthermore, the lawsuit asks that the court assess a civil penalty of $50,000 per violation of the Illinois Consumer Fraud Act, additional penalties of $50,000 for each act committed with intent to defraud, as well as penalties of $10,000 per violation committed against a person 65 years of age or older. Finally, Madigan asks that the Defendants be required to pay $1,000 for each willful or negligent violation.
