Standard Bank - Personal Banking...poor service Mowbray Branch and OTP, ***** and Online banking

Spent multiple hours in the bank over the last two business days trying to resolve OTP, given the bank in Mowbrays failure to help assist gaining access to my account. I have been promised transaction access both on Friday and again today (after two lengthy consultations and visit, the suggested route has not resolved my issue for a second time). I cannot transact and have missed multiple important transactions like a bond payment and school fees and have an unresolved issue lasting for 72 hours now. ********** (office hours), or email.
