In XXXX XXXX, I moved out of the apartment I was sharing with XXXX others and, among other things, ended my XXXX service at that address. XXXX picked up the equipment and the final bill that I knew of was paid. I have had XXXX services at multiple addresses in multiple cities since then. When I moved to XXXX XXXX, I was told I could not get an account because I had never returned my equipment from that first account. When I disputed that with the representative, he said he would look into it, and shortly thereafter I was offered a contract to get service, and I opened a new XXXX account in XXXX of XXXX. I have had XXXX service continually since then, have paid my bills on time, and have never had any issues mentioned to me by the company. On XXXX XXXX, XXXX, I received an alert that there was a new open collections account on my credit report. I went to check and found, after much investigation on my own part, that Southwest Credit Systems had placed a derogatory mark on my credit score for a {$65.00} debt to XXXX which XXXX was alleging I owed from XXXX. I have had the same name, phone number, and social security number affiliated with all of my accounts with XXXX, so they have no excuse for this absurd behavior. They have never once contacted me, sent me a letter, billed me, or otherwise attempted to hold me responsible for this amount. Southwest Credit Systems never sent me a letter regarding my debt before placing this on my credit report, and has made no contact with me whatsoever at this point, rapidly approaching their 30 day deadline. I am sending them a demand letter for verification and other information pursuant to the relevant federal laws. I do not believe I owe XXXX this money, and dispute the validity of any debts to XXXX and any collection agency regarding this amount.
