Third time's NOT a charm with Standard Bank!!!

Is it the prestige bankers in Standard Bank or is it the bank itself which sucks? They sell prestige banking as a 24/7 service, but contrary to that, they let me down for the third time now. First, when I was desperate to access my money while in the UK. Second, when I complained about prestige banking after realising that it was a useless service when I was re-directed to normal banking channels. to make that worse, I was in the process of purchasing property and Standard Bank apologised for the inconvenience they caused me and said to make up for that, they guaranteeing me a successful application of 100% bond, which came at a whopping 13.9% interest rate while prime was 10.5% at the time. Thirdly, as I write this review, I have not received a reply in over two months from my email to the Standard Bank prestige banking about the inconsistent charges on my credit card and the re-evaluation of my credit limit following my lump sum payment. It is probably even pointless to write this review because they have shown countless times that they do not care about their small clients like me, even after 15 years plus banking with them. This probably calls for a bank switch.
