Uncaring and rude service from call centre with no concern about the fact that R1700 is missing from my account.

I purchased a monthly Amazon Prime subscription this afternoon, but when I wanted to use my card later, I noticed that a deduction for a monthly subscription AS WELL AS a deduction for a yearly subscription was reserved on my account. I called the Capitec Call Centre where the first person told me that she was going to transfer me to card disputes and then the line just got cut off. I called back and spoke to another guy to who I had to explain the entire story again. He told me that there was no card disputes department and that the matter would simply be logged and investigated. When I asked him when I could expect to have the money back in my account he told me "there is no guarantee that you'll get the money back. We first have to investigate." When I asked how long that would take I was informed between 7 and 14 BUSINESS days ie 3 weeks. I then actually called Amazon myself and they told me that they could find no trace of the transaction for the annual membership on their side and that it must have been "SOME SYSTEM GLITCH." Because they can't find the money on their side, they can't refund me, but told me to speak to my bank who should be able to take the money off hold immediately. When I tried to phone Capitec customer service back I just kept getting more options to press and was kept on hold for such a long time that I eventually gave up and decided to try and call them via some other means other than telephonically.
