How to get rid of someone else's debt collector?
I have been in a similar position for quite a while now and the only thing that seems to help is screening phone calls. I have a long list of collector numbers set to not ring on my phone. They can still leave a voice mail but they never do.  As far as I know there aren't any laws that protect you from nuisance phone calls. FDCPA letters only apply to the debtor and the collector it is sent to it doesn't protect an unrelated third party from getting annoying phone calls. I have a feeling that sending FDCPA letters is just confirming that you probably are the debtor and prolong the collection calls.
