Bad Service in opening an account

I had convinced my husband to change his banking account to FNB, but it has been a constant battle to get the account going 1. They have the wrong cell number for the OTP, tells us it is going to take to 48 hour if we want to escalate it 2. We must go into the bank to change this, what happened to the whole digital and you are making banking easier ?? 3. The Cheque card is still not delivered, the company that needs to deliver it has an excuse each time the promised delivery had not taken place, it is now since Friday 8 March 2019, today is Friday 15 March 2019, and today the new promise is the card will be delivered Monday 18 March 2019 ??

I am struggling to justify why he should move to FNB if the service he is getting is sooooo bad, and what is FNB going to do about it?

We need a letter of proof of the account for his salary department by today so what is going to happen where should he pay his salary into then ? (Wanted to do this online but with incorrect OTP number we cannot)

Can someone please assist on this nightmare ??
