Appalling service by Audi Center centurion and Ernest Manamella

On 1/11/2019 I purchased parts from Audi center centurion. They had to be ordered and would take 48 hrs. I paid and left. Hardly an hour later, I came back and cancelled the order as another dealership had them readily available, so I got them there instead. The sales consultant Jacob maila requested I bring proof of banking details for the card used when purchasing, which I provided in less than an hour. They confirmed that the refund would take 24hrs. I waited in vain until I followed up with them on 11/11/2019 only to be told that there they need another proof of banking details.???? Why was I not informed of this Why would no one bother to follow up with me to see if all was resolved, obviously someone knew about this requirement,yet I was never informed until I followed up. I promptly provided the banking details again and was told that money will be made available this morning. I STILL HAVEN'T RECEIVED MY MONEY AND NO ONE HAS BOTHERED TO CALL AND ADVISE OF PROGRESS. I followed up again and asked to speak to Jacobs manager, Earnest Manamella, he seamed very uninterested in what I had to say. While I was explaining the situation, he said I must hold on, he then proceeded to have side conversations with colleagues where I could hear laughter in the background. Then the phone was cut, a minute later Jacob called to advise me that Earnest just handed him the phone and said he must sort me out. Obviously I still didn't get any joy from Jacob, thus my worry that what is the point of escalating a matter to management if management will also be not helpful. Jacob was never rude or anything, it was his manager that I was unimpressed with him being rude, unprofessional and obviously ***********. This is a simple matter of a refund, how does it take almost two weeks to be sorted out. This whole incident makes me question the training and suitability of the management and their specific tasks at hand. I will wait for my refund until 2pm, if not received, I will be taking this matter further to social media as well as senior manager at Dealership and Audi SA. Such behavior is unacceptable.
