Charging of services not rendered

I am very upset with Game. I paid my account in full at the Somerset West Mall branch on 12/09/2015 at 09:13. Tracy was the cashier. I asked her several times to unsure that the account has been cleaned and closed so no more accounts are received. She ensured that it was done. But to my surprise I have now received 2 accounts from Game for Services fees!!! I would like to know what services were exactly rendered to me??? I too work in financial services and something like this is unacceptable. I do not see it fair that I should pay for something that is being charged due to an *********** employee. I sent Game an email on 30/11/2015 explaining this whole situation and asking them to resolve this matter. I received a reply saying I would receive feedback within 48 hours. It has now been 4 days and I have received nothing but an sms saying I need to pay my account. I expect Game to write-off the money they are planning to \*****"from me. Because that is how I see this"
