Utter pathetic service from Discovery. I'm taking my services back to anywhere else.

Opened cases and no feedback from Discovery. I have logged 3 cases dating back to 25th July 2019.The case numbers are as follows:

1. 59035 2. 42598 3. 40666

For each of them I was promised that a Discovery Banker was going to contact me - nothing doing. To this day (8th August 2019), I'm still awaiting. In addition, when you call Discovery and have to hold on for over 10 minutes, you're encouraged to make use of the internet banking site www.discoverybank.co.za - that site also doesn't work. It's non existent. How do you provide an alternate non-existent channel??? How do you provide a fully digital banking experience when you can't do the basics right ? Is it right to wait 2 weeks for feedback on a case that you've logged? And I'm paying for this **** service ???
