They called many times, no message left. Very annoying. .

Have they came by your house any?

These are lowlife debt collectors that buy out of statue of limitation debt for pennies.  They are not legal, just trying to use scare tactics to get any money they can out of you.  Do not fall for this, do not give out any financial information.  File a report with the FTC and the new Consumer Financial Protection Bureau.  No one is going to call you and let you know they are going to serve you papers, it is a scam.  Next time they call tell them you are recording them, reporting them to the FTC and CFPB.  They are not legitimate.

Dido, I missed a call today from this phone number.  I called it back and it just kept ringing with no answer. I do not have any more information but will add this to my scam contact list so my phone will not ring when dialed from this number.

Same game just a different number. They go away for awhile but always come back. Sick of the calls. I no longer have voicemail on my cell bc of these scammers. I got sick and tired of their nasty, rude, threatening messages. I reported them to the Attorney General but they are "spoof" calling and no one can trace them.
