I received an invoice in the mail a couple of weeks ago from a collections agency saying I owed $84. I had no idea what it was for, so I gave them a call. Turns out some phone sex place says I made a call in 97, and it has now been turned over. They were able to give the originating phone number, and I have never heard it. I sent a dispute letter, and just got another letter today. This one says I should be able to pay it, and they are going to submit it to their attornies. What the hell can I do about this? The call was supposedly made when I was an hour and a half away at school.
