Waiting for more then a day to open a straight forward savings account - is this normal?

On Sunday I went to open a Savings account at Nedbank Mall of Africa. All paperwork was completed and signed. The application status then said that it needed to go for another verification. The consultant informed that it was no reason for concern and that he would send me proof of account before they close on Sunday or at then latest then Monday morning. Monday morning I started to find out what is going on, I did explain that I need the account confirmation as a matter of urgency on Sunday to the consultant as well as to the other consultants I spoke to on Monday. Eventually the complaints department assisted that someone from the branch contacted me, the lady asked me to send a copy of my ID again, which I did. At around half past 3 Pieter from the branch phoned me to say that there was some sort of system error. At this stage I could not go to another bank as it was to late. I was informed that they will get back to me tomorrow. I do not understand why I must wait for more then a day to open a straight forward savings account. It has been the most frustrating experience in the my life.
