Terrible service at The Glen Standard Bank

I am very disappointed with the service received from the Glen Standard Bank last week Friday by a Business Banker called Priscilla Naidoo or Singh, my apologies I don't remember her surname. However, she welcomed us with a smile and believed we were in good hands. She asked that she call us back after 2 hours once she has completed the business account registration as it takes about 2hours to complete. We believed she would, but gave her a grace period and believed she would come back to us, seeing that she was friendly towards us. She further said its not advisable to come in on Saturday as the bank is busier, she didn't inform us that business bankers do not work on Saturdays, the contact centre informed me on that. I have been calling the contact centre this whole week but it has proven to be difficult to get a hold of her. I work in Vanderbijlpark so chances of popping in there are slim as I knock off at 16:30pm and the bank closes off at 15:30pm. Until now, I did not receive a call or a missed call from the bank or her informing me of the progress. Now, how does such a big bank like that we trust with our businesses treat its customers like that. I am very disappointed to say the least. Now we might have lost deals because of her delay.
