The RCS service refuses to close paid up account

I have made several requests to have my account with Game closed over the past month without success. The account has been paid up for over a month now and I had an amount of R283 owed to me. I was asked to give a number of documents in order for the refund to be processed which I duly submitted. I still have no response with regards to the closure of the account instead I noticed that the amount owed to me had decreased to R143. I really dont know what is going on as I do not believe closing a paid up account is rocket science. I believe RCS is acting greedily as they want to continue charging me for paid up credit that I no longer need. This is also negatively affecting my credit score.
