I regret opening a RCS/Game account

I have the worst experience ever with RCS and game stores, I played my account at Cape Union want to close it and they say they have not received my payment. Their communication channels are Si bad, the never call customers to inform them about queries. Recently I played for a bicycle and they did not have stock, even now I have not received a call from them, but I played for the bicycle. I regret shopping at this store and advice consumers to not do any businesses with these people.!!!!!!
