Bad servicing from Discovery bank

I had moved my discovery/FNB credit facility to the discovery bank. The application process was rather easy. But everything after that has been terrible. I was waiting for my card and then a discovery motor card was sent to me in error. Then I called to enquire why this happened. They admitted it was a mistake and that my new credit card will come in 2 business days.

I called again after 2 business days and was told there was a mix up in cards being delivered and it will take another 2 days. Another 2 days passed and no card. I called the delivery service and they told me I wasn't on their system. Highly frustrated I called discovery and they told me about the same mix up and now there was no time on when I'd get the card.

I asked for an apology letter from the consultant Akhona, who said she would escalate to her team leader. It has been another 2 business days and no apology letter. I have asked for nothing special but an acknowledgement of their poor service and I can't get that.

Really bad service for someone I'm trusting to bank with :(
