Having a hard time to close my game account

I payed off my game account , sent them a proof of payment about 4 weeks ago.I called once the payment updated to request for an account closure and i was told it will be closed on the 12/05 due to statement run , i was shocked when i called today 15/15 to find out that the account was not closed instead they are busy trying to retain me instead of actioning my request.Game please close my account i dont need it and this also dampens the chances of me being a future prospective client as they are giving me a runaround for doing something as simple as closing the account.This is really frustrating.
