Game account biggest mistake of my life

I have settled my Game account more than two times. I keep getting outstanding amounts even when I am not using the account. I have settled it twice this year and attempted to close it 2 months ago. To this day the account is still not closed. They even listed me at ITC for not paying, I had ignored payments because I don’t know where the amounts I owe are coming from. A few weeks ago I decided to settle it once and for all as the listing is now blocking me from getting a credit card. I have called the call center numerous times to try and get the account closed and for them to give me a settlement letter. I keep being told they have emailed my request to the account closure department who should call me in 48 hours. To this day they still haven’t called. Where do I go to get this account closed?
