I ran my credit and saw that I had a neg account under Convergent Outsourcing in XXXX, WA. I called to find out what this was and they claimed it was a XXXX account. I did have a XXXX account but closed it because they kept overcharging me from what my plan agreement was and for apps I never ordered. I paid the bill at just under {$600.00}. CO Inc. claims I owe {$1200.00} and it is on my credit report. First I asked them to prove to me the debt, they refused and told me I know what it is and second they would not talk to me unless I paid in full at that moment. I filed a claim with XXXX, and disputed with XXXX, XXXX and XXXX. They still claim I owe it and wo n't budge. This is on my report and I do n't owe the {$1200.00} they claim I do. When I called again this week they told me I had to go in a website and they would walk me through. It was really strange and the account # was not what is listed on my credit report. It just seemed really shady. I want this off my credit report because I am a XXXX and trying to buy a home.
