Account charges

So disappointed with the game account, i paid off my account in August. Every month I'm getting outstanding balance of the same amount. I called customer service twice already and the past months I paid immediately even paid extra after being told it will be the settlement amount, and its the same amount I just Got another statement I can't be paying again! I need my account to be investigated, and statement reflecting all amounts paid.

Im not impressed at all and I wish to close this account!
