POOR SERVICE AND NO CUSTOMER CARE AT ALL @ GAME STORES

I am so disappointed in GAME stores, I have been trying to close my account there for weeks and no one has been getting back to me. When I went to the Game at Cape Gate in Cape Town I was told to contact the call centre. No one picks up there and you hold for long periods. No one responds to my emails either. I am so frustrated, I want this account closed as I do not want to be charged interest. I do not know how I can have this account closed. SERVICE THERE IS TRULY POOR AS IF THERE ARE NO MANAGERS OF SUPERVISORS THAT MONITOR EMAILS.
