Discovery Bank is not a real bank. All promises but no delivery

My Discovery Credit card was moved from FNB to Discovery Bank without properly informing me of the changes. When I transacted online, I used to get my OTP via email as I work outside of SA most of the time. Unilaterally Discovery Bank decides that sending the OTP to my email was not allowed and they started sending the OTP to my wife's cellphone number which is in SA. I called Discovery Bank at great cost from outside of SA and was informed that a consultant will call me back to sort it out. That was two weeks ago and no consultant has called. Today I called again and after speaking to the consultant, the line was cut or put down in my ear, I don't know. Stranded outside SA I have to go to great lengths to get the OTP from SA before I can transact. Thanks Discovery Bank for a 3rd rate service. I will be closing my accounts... PS. Don't try calling me on my SA number. Like some of the reviews on Hello Peter about Discovery Bank, I suspect the bank will not answer
