Discovery Bank difficulties

I read various poor reviews on Discovery Bank and decided to decide for myself. I attempted to open a bank account. They did not accept my lawyers letter with proof of my new address for Fica. I explained that I recently purchased a property so had no record of any statements of account. I attempted to get an affidavit but left the police station empty handed after 2hrs. I returned the next day and was successful obtaining an affidavit. I submitted it. I heard nothing. I then phoned after waiting all day for correspondence. I explained I wanted to move my bank. I was cut off after 15 minutes of waiting for the Fica department. I phoned again, asking that they return my call. I verified my details and am still waiting for their call, half an hour later.

I need to trust the institution where I invest my money.

What can be done? They are making it challenging to do business with them.
