Rude staff and call dropped

I have been with Standard bank from day 1...only bank I have been with. Over the years I have accepted that their service is terrible and the only reason I have stayed with them is because they have branches and ATMs everywhere. Online banking means I interact less with their staff. It seems they are working hard to make their service as bad as possible with rude staff (they are ready for a fight even when all i need is an explanation, like why did you not take your debit on the last day as per the contract only to call me 2 days later asking ME why STD bank did not take their debit. Who came up with the idea to scream your selected option when making a call only for the lady to say "sorry, i did not get that' then repeat the options again if your scream was not loud enough (worse if there's people around you). after a few attempts its back to press 1 or press 2

My main issue is that I cannot make online purchases because I cannot get the OTP to complete the payment (says number does not match the account when I enter the tel number to get the OTP). I receive SMSs for all other OTPs (paying on the app) but cannot get for debit card or instant payment.

I have called STD bank but after trying to scream what option I choose a few times the staff just drop the line either while getting transferred or the last call someone did answer and as I was stating my case the call got dropped???

Its 2022 and there is Tyme Bank that proves that if the tech is right we do not need to deal with rude staff. I just want my number to work when making online payments.., Can someone assist...I have missed out on deals as I cannot make payment
