Interest

I received my statement from Discovery for a balance of around about R6652.80 for my credit card.<br> on the 9th June 2015 I settled the full amount leaving my account in a zero balance, intending to close my account. I then sent a cancellation request<br> i received a statement on the 15th June with interest of R120.60 being charged on my account!<br> I then contacted the call centre to have the interest waivered and was told by a consultant its for the balance at 1 June 2015. I requested to speak to a manager waited for -5mins and still no manager to speak to.<br> I am certainly not a happy chappy about this!! <br>
