A contract from Hell with RCS

I have called RCS customer care line(07/02/19) for settlement amount and paid it on the (09/02/19).I went to Game to confirm whether my account has been closed on the (12/02/19) and was told I will receive termination letter through e-mail within 36 days. I have not even received it even now and all I receive is an account bill stating I'm owing them R200.11. I have visited the Game branch 2 times since and got reference number ( ********** 02649) on 16/04/2019 assisted by Kylen and then ( ********** 01389) on 19/05/19 assisted by Erin. Both of them told me they will reverse the amount charged and the account will be closed. I will receive an sms to confirm. I'm surprised even now I've just received an sms from RCS that I should pay. I feel defeated and I regret having a contract with RCS.
