REFUSING TO CLOSE MY ACCOUNT INSTEAD REQUESTING MORE MONEY EVERYDAY.

For weeks now I have been requesting an account closure myGame store card to no avail, instead I keep getting requests to pay more. I called in on 30 July, got a settlement statement and paid on the same day but now all of a sudden I need to pay R80,39 again to have my account closed. What happened to the settlement fee I have already paid? Who did not do their job to close the account upon receipt of the funds, I paid within the 5 days stated on the settlement letter yet my account is still not closed. I WILL NOT PAY ANY MORE MONEY, WHOEVER FAILED TO CLOSE MY ACCOUNT ON TIME WILL PAY, I DEMAND A PAID UP LETTER AND NOTICE OF ACCOUNT CLOSURE.
