Internet Banking - Change of Cell Number and getting OTP

So I accidentally blocked my standard bank app on Saturday 4th Nov and when I wanted to reset my password, it was sending the OTP to my old cellphone number. I then went on Monday 6th to the Belhar branch to change my cellphone number. They told me it would take approximately 2 hours before the service would be active. They then put me through to the customer service on ***as they said I needed to activate my OTP for the new number. The customer service agent then advised that I change my ATM pin (No idea why)

I called the customer service again on the 7th Nov as my profile was still blocked. This time on the App and Website, it said I needed to activate my OTP by calling the customer service number. They then said their OTP system was having issues. So I called again, today 8th Nov, explaining to the lady over the phone that I would just like to have my OTP service activated. She then says that according to her Manager, I need to go into the branch to do this!!! Clearly on the website when trying to reset your password it says "Please activate your OTP service by calling Customer Care on ***"!!

I have been with Standard Bank since 2011 but ever since this back and forth I will be moving to another bank. I have been without internet banking for 5 days now and I just get shoved in a circle.

Pathetic service.
