Account still open, after requesting closure

Absolutely pathetic and appalling assistance. I've been to the Gateway branch and paid my account in full and asked for it to be closed. The account was paid and now I get sms's stating that my account is now in arrears. What kind of **** is this from a big store like Game? I would not recommend anyone to open an account with Game as you can purchase an item for R500, they will change you 150 per month. Out of that 150, 20 will go towards your account and the rest will go for charges so, they can bill you for 2 years on the same item.
