Who these people are, or were, beats me--they hung-up, @ the same time someone else put down the receiver after telling me I have a call--I told them I was still there, but they were gone.  Some sort of civil suit, or summons, that's about all I got.  I called them back twice, no answer, although the answers seem to be right here  aw

Called to say my husband had to appear in court for a civil issue next week,  they would be bringing papers by tomorrow.  I said I had never heard of them,  was too tired to wrote down info,  could they email it to me . She said she would call back and leave a vm, they don't email.  She never called.  I tried to call back later,  no answer.

This is a common ploy by criminals masquerading as debt collectors who are attempting to extort money from people by scaring you into believing that you will be criminally charged, go to jail, lose your driver’s license, have wages garnished, be sued, and a variety of other variations on this,  all for an alleged or nonexistent debt.  One of the tricks they use is to call your work place, friends, or relatives repeatedly in an attempt to shame you into paying.  They also use the “process server” ruse who calls and claims he is going to serve you, but then says you could avoid it by calling another number

Federal law (FDCPA) requires them to send you a letter (US MAIL ONLY) postmarked within 5 days of their first contact that contains their name, physical address, the creditor’s name, and the amount of the alleged debt.  It also must contains “mini-Miranda” telling you that it is an attempt to collect a debt and that all information will be used for those purposes.  The one other important thing that this letter must also have in it is that you have a right to dispute the debt within 30 days of receipt of the letter and if you do so, all collection activity must be stopped until the debt is verified.
