Poor service

Good day,

My husband is with Standard bank for years. His number have changed so we had to physically go into the bank to update his new number. In the first place he doesn't have enough time in a day to do that, we ended up doing it three times. And still we do not receive our otp messages for online payments. We prefer online payments because we are busy. Now my husband once again has to go in to hopefully get it right this time. Our problem is time, lunch is only so long.
