DO NOT WANT TO CLOSE MY ACCOUNT IMMEDIATELY

I went into Blue Route Mall Foschini on the 29 June 2015 and settled my account and asked them to close the account. The lady phoned client services and spoke to a Melissa. Melissa advised the lady that the account cannot be closed immediately only by the 16 July 2015 and only there after at the Credit Burro. I also requested a settlement letter which will be emailed to me. She then said I can phone client centre myself which i did and spoke to Noma (***) she advised me the same thing she had no reason as to why only that this is the Foschini Groups standard procedure. If I go to ABSA Bank or any Financial Institution to close my credit card they do so immediately why must I wait for an legal account to be closed on my name and wait for this to be updated on the Credit Burro. Yes I have been told the card has been blocked and cancelled however not closed and this is not good enough I want this account to be CLOSED with a settlement letter. Is this not my right as an Consumer? Please close my account and update details on the Credit Burro. If my account is not closed and updated I will contact the consumer council to assist me in closing this account.
