This is a collection agency, and apparently they try to double-dip on debts that have been already paid or have exceeded the statute of limitations. Superbob has the right idea.
Called, left no message. We also received a call from them from 2155546482 about a week ago according to the caller id. Here is says they are a collections company but we don't owe for anything. I saw elsewhere the number was being spoofed for scammers and we get calls similar to what those mention all the time so who knows what's up with these goofballs.
Many phone calls to me and won't say anything when I answer the phone. I've been completely out of debt for the last 24 years. I don't have a clue why they would be calling me. The least they could do when I answer is say something instead of just haning up on me. I consider this harassment and would like to report them to the authorities.
