they called me a number of times from the phone number 3348767560 trying to say i owe a payday loan company which i do not

I have been receiving calls from an Alabama number 334-876-7560 harrassing me about a payday loan I supposedly took out.  First he claimed it was for $94 but later claimed it was $241.  The man spoke with a foreign accent and first called himself Steven Jones and then Steven Parker with Case Callers.  He claimed his address was 425 Park Avenue, NYC, NY.  When my husband asked for a supervisor, he had none and he did not want to resolve the issue.  We explained repeatedly that I was not the person he was looking for.  I Googled Case Callers and there was nothing.  When I Googled the number and got this post and let him know that we knew he was a crook and the FBI was investigating he hung up.

I have been receiving phone calls from this number for about a month now.  They say they are collecting for a payday loan which I supposedly took out.  Different people call me with foreign accents, possibly East Indian.  The only name I have gotten so far is Dan Castillo.  They have also called my sisters and asked them informatiion about me.  One caller threatened to have me arrested and another one says they are filing a lawsuit on June 14th.  I have reported them to the Attorney General of Oregon but have not heard anything back.  Hopefully, someone will take note of this and give me some answers.

I have not received calls from this number, but have from 321-275-5254, 415-880-5599, and 505-807-2770. Them they say I have taken out a payday loan from Ten Dollar Payday Loans. tThey give you 334-876-7560 as the loan company number. They also tell me they are filing a lawsuit with the local court on June 14th also. I have called the real loan company and they are working on getting information to file a lawsuit. I have a lot of different names they use. I have called the police.

My sister received a call from 321-275-5254 asking for me and how to get ahold of me, when she would not give them any information, they threatened to come to her house and kill her family.  We called the police immediately and they said it was most likely a bill collector who has outsourced their company.  They suggested changing our phone numbers and not answering the calls anymore.  This is total horse [***]! I want to know what company this is who has outsourced and have them shut down.  The police said that if we can find out the company's name, they can get into serious trouble.  If anyone has any information about this, please share.
