Account closure

I have an account with Makro which I've been paying on a monthly basis. On 21/09/2015, I decided that I wanted to settle this account & called Makro Customer Service where I spoke to Sunaina. Sunaina confirmed that my full & final settlement as at 21/09/2015 was R9508-51, which I paid via EFT. I cautioned her that I intended to close this account & she advised that it would take relatively 3 days for my payment to reflect on Makro's account. On 28/09/2015, I called Makro Customer Service and spoke to Colleen (Call ***) and asked her to close my account and also send me confirmation of closure via email. Colleen advised that I should email my request to [Email Removed] which I did the same day. Since then, I've been battling to obtain confirmation of closure of my account from Makro. On 05/10/2015, I received 2 emails from [Email Removed] requesting copies of my ID & banking details, bank statement reflecting my debit order & receipt of the payment I made, which I sent. But todate, I still haven't received any response. I've had bad experiences in the past for not closing accounts & only want Makro to close my account & serve me with confirmation.
