I received a letter dated XXXX XXXX, XXXX from Fidelity Information Corporation for a an outstanding balance to a XXXX that I do now owe. I responded via certified letter mailed on XXXX XXXX. XXXX disputing this balance and requested verification documents. The certified letter was signed for on XXXX XXXX, XXXX. I specified in the letter that I wanted written response. I have not received any written or oral communication with this debt collector until XXXX XXXX, XXXX at XXXX. The agent said she was with Fidelity Debt Collection and was attempting to collect a debt. I told her I had an open dispute and that I mailed a certified letter back in XXXX. She said she had no record of that letter and that it was impossible since they just received the account in XXXX. I then read her the letter that I received from Fidelity Information Corporation and the date. I also told her of the certified letter I sent. She said that was a different company and the XXXX companies had since merged. I told her that was not my problem, since I still have never received any materials and that I also requested to only be contacted in writing. She eventually hung up on me. I called back attempting to sort the matter out, they asked for verification of my SSN and I told them no, as there would be no way they would have my SSN relating to this balance as there was never a contract or documentation with my SSN or DOB. I told the agent that if she verified she had my SSN that I would verify the last XXXX digits, she then verified that she did not have either pieces of information. I then spoke to a XXXX XXXX that informed me that they would come after me with this debt and that the letter I sent meant nothing since it was with another company. I then told him to not communicate with me except in writing and that I would be contacting my attorney regarding this incident.
