I was contacted by portfolio Recovery Associates, or at least they claim to be. The lady claimed to be trying to collect a debt from XX/XX/XXXX. The debt was originally with, supposedly, XXXX XXXX. They stated that it was charged off in XX/XX/XXXX. And that portfolio recovery Associates picked up the debt. In XX/XX/XXXX, I pulled my credit report and with the assistance of a loan professional, I went in and paid off all debts on my credit report. At that time, if there were an outstanding bill from XXXX XXXX, it would have shown up on my credit report and it would have been paid at that time. I did tell the woman I was speaking with that I had paid everything off my report in XX/XX/XXXX. She informed me that this debt would not have shown up on my credit report, but that it was a debt and it needed to be paid. I told her that I did not feel comfortable paying a debt from XX/XX/XXXX and that I could not verify by looking at my credit report. She repeated to me several times that it would not show up on the report. I told her that just did not make sense to me. She stated an unfamiliar address, an apartment address. I have lived in apartments in the past, but I did not recognize that address. I told her that address could have been a made up address. She was unable to tell me the phone number that the bill belongs to. I told her that I did have a landline in XX/XX/XXXX, but in XX/XX/XXXX everyone basically had a landline. I told her that it did not make sense. Long story short, she repeatedly requested payment and said it was my debt. I told her that I did not believe that was my bill, it could not be verified, and that I was not paying her any money. She stated that she was going to notate that in my record, and to have a good evening.
