Double charges on my credit card - Case id: ***7

ON 21/09/2017 i sent the below e-mail:

I am being charged twice for a credit card account fee, last one being R18 & R31 on the 21/08/2017. I called and was told that the second debit is for a petro card. I did not apply for a petro card and don't have it. The person i spoke to told me that it has now being cancelled. Can you verify that and reverse all the deductions done for over a year. I've called 3 times already and logged a query on the website, to no avail.

ON 21/09/2017 i received feedback saying it has been cancelled & refunded. I further sent an e-mail on 22/09/2017 stating that only one moth payment was refunded, but never received any answer. I sent another e-mail on 27/09/2017, to date still no reply
