Allied Interstate ripoff Mesa Arizona

First of all, you need to read up on the rules and regulations for collections (I think that's on the FTC site). Second of all, if this is not your bill and you know it is not, send them a letter stating that same. In the same letter, advise them they are to cease and desist contacting you (certified mail, return receipt requested).

Get a recording device for your home phone and tell them every time they call you are recording the conversation (check the laws for your state and the state where the collector is calling from...it may be legal for you to tape record the conversation without the other party's consent).

If they are calling you at your office, have several co-workers come over to your desk, put the call on speaker phone, and tell the collector calling that they are on speaker phone. Some people might be ashamed to do this, but if this is not your bill then you have nothing to be ashamed about.

If they continue to contact you after receipt of your letter, then contact the local authorities, the FTC and update your Rip Off Report.
