Endless disappointment regarding Game card

Due to lack of information and poor service I received regarding the game card..I decided to pay it off and settle it upon receiving settlement from contact centre on 29/04/2019 on 30 of April I called in to let them know I have settled the account, I was told someone will call me in the next 48hour to confirm and no one did a week later I made another call again which I was told the samething and still no one called .I checked my game app and it shows I need to pay R79 now for what ? why must I pay an account I have already settled..I'm very disappointed in the service I got regarding the game card..I'm not willing to pay anything extra than what I have paid for settlement already ..I need this account close emmidiatly ...or maybe I should consider contacting the consumer ombuds for help.
