Your phone rings 24/7 and shows no sign of stopping, but if ever you should pick up, all you hear is the incessant yabbering of a telemarketer or nothing at all. You're infuriated by the anonymous calls jamming your phone line. Is there some way of finding out who is on the other end? Do you pick up or leave it ringing? Who is calling?

      Jumps straight to VM, leaves a LONG message regarding that you are in massive debt and the attorneys have been trying to contact you and calling you constantly. I have been getting these calls at least four times a day. DON'T FALL FOR IT. Block and delete.

    3. Crystal reported Mark/ Michael with the number 7272954557 as Aggressive advertising

      Phone never rang. Got a voicemail from a totally different number than the call back number from a guy named “Mark” calling about “student loan forgiveness”. I don’t have student loans. So as if that’s not sketchy enough about an hour later got a voicemail no missed call from a different number. The guy had the same exact voice but this time his name was Michael and he called for “debt collection” lol. Different callback number too. I don’t know what scam this guy is trying to pull but beware. Definitely a scammer.
