Discovery Bank sucking every cent out of YOU!!!

After 2 major errors committed by Discovery Bank on my account and due to the huge inconveniences I experienced with the app and product, I decided to cancel. I had just missed cancelling effective 31 Dec and dutifully paid more fees but sent a cancellation request to info@disvovery on the 10th Jan - no email address for them. Email was referred to administration@discovery but no response. 2nd email was sent 21st Jan and now in capital letters. NO RESPONSE. Now I'm slapped with another bill and STILL NO RESPONSE!! So much hype for so many years and they can't even get the main aspect right - commicating with the client!! I've moved my business back to FNB - no hassle. Now almost 2 months later I'm still struggling to get out of Discovery Bank's grip!!!
