Behavioral bank's poor behavior.

I received an email saying they will phone me to move me over to the new Discovery bank. Untill today nobody phoned me. Then my card expired and I couldn't access any of my money. I phoned Discovery and asked to be moved over to the new bank. They advised me to download the app and Register. Then someone will phone me. I did that 2 weeks ago and nobody phoned me yet. I then decided to cancel the account. I was promised someone will phone me within 5 working days to cancel. I still haven't had any feedback from Discovery. This level of customer service is totally unacceptable.
