DISGUSTING CUSTOMER SERVICE DISCOVERY!

I have now emailed 'Discovery card' / bank 12 times!!! I had a query. Eventually, i emailed them saying ' if you cannot have the courtesy to call me back, or email me, you can close my account. They emailed me back with instructions on how to close my account?!! They never bothered asking WHY?? It seems that Discovery bank are on a drive to irritate and ignore current customers! After a month of emailing, asking for a manager to contact me, i got a call from a consultant. I repeated that i wanted a manager to call me. 2 Two weeks later, i am STILL waiting!!! This month they double debited me for my card fees. Discovery bank must offer the ABSOLUTE WORST customer service EVER!!!! I want to move my medical aid and bank account from Discovery!!!
