Standard Bank - Unreliable & Cant Help

I changed my cell number and needed to update my profile with my new cell number details. So I went to Standard Bank at Clearwater mall to update my details in April 2022. The change of number reflects on my mobile banking app, however the OTPs are still being sent to my old number. So I went to the branch again last week on the 15th June to update my umber AGAIN, and yet the OTPs are still being sent to my old number! I cant make any new payments, I cant add any new beneficiaries, I CANT EVEN LOGON MY INTERNET BANKING because it askes me for an OTP sent the my OLD nr!! I am super frustrated. How can I trust you with my finances as you are clearly in charge of my profile and accounts and you call the shots not me- How am I suppose to do my banking?

2nd of all I also took this up with the branch when I was there last week - I cant access my Notice deposit, It does not allow me to wait for 30 days or withdraw immediately, Which I find so unfair and unreliable. A bank I though I could trust, A bank I though would help but absolutely nothing was done to help me.

My OTPs are STILL being sent to the wrong number Cant access my notice deposit!

Due to this you have wasted my time, my fuel to get to the bank, and parking money to try sort this out but Standard bank some how is refusing to try make an effort at all to help me or change my details. Its just been a stress and a horrible experience.
