Refund query on Absa credit card

Goodday<br> In late November 2015 I got a call from Absa advising me that they are refunding me on my credit card as interest was over charged and they need to confirm my savings account details. I've confirmed it and was told a consultant will contact me. On 9/12 I followed up and spoke to Petunia who said she will follow up and come back to me. This never took place. On 10/12 I phoned and spoke to Marcia and she confirmed no feedback. On 17 November I spoke to Cheslyn who again confirmed my savings account details for the refund to be credited. On the 11/12 I spoke to David - 15/12 to Nevash and 23/12 to Xolani who eventually escalated the matter and advised it will take up to 48 hours to be resolved. On 28/12 i spoke to Zain who advise theres no feedback but will follow up with Xolani. On 30/12 I followed up again and Zain advised he will ask Xolani to contact me which never happened. 31/12 at 11 I followed up again and spoke to Xolani and he advised no feedback but will come back to me. Nothing happened. Spoke to Cheslyn this morning no feedback aswell as to Zain. I'm not sure what Absa staff understand under customer service as nobody comes back not even a email. I have to phone.
