OTP

I relocated to the Uk 2022 and before I left SA I went to the branch Carlton centre and asked my OTP preferences to be changed to my email address. I got to the Uk to find out that they did not change it, I called them to resolve the issue but they said they couldn’t assist as I had to book a flight back to SA for them to assist me in the branch. June 2023 I went to SA, standard bank OR Tambo, they said they had sorted it out but when I got back to the UK it still wasn’t working. January 2024 I went to Standard bank Sandton mall, they said they sorted it out, I even asked the consultant assisting me to remove my old number as I no longer used it. He agreed and said he had sorted it out. February 2024 back in UK I try to transact the OTP still goes to my old SA cellphone. Am so disappointed, actually am disgusted with this ******* service . I have called numerous times to get this sorted but nobody seems to know what to do….just to put the damn OTP preference to email has taken Standard bank a damn good 3 years…absolutely diabolical
