Lack of staff is shocking

What should have taken me 5 minutes to do in the brand took me minutes due to lack of staff. There was only 1 consultant available to assist a que of more than 15 people. I asked the lady why she was the only person on duty and she rep**** that the rest took off or phoned in sick, pretty convenient for the last working day before the long weekend. The people in the que was agitated and started voicing their anger to this 1 person who had no control over the situation. They also started arguing amongst each because everyone had somewhere to be but had to wait and people started jumping the line and causing trouble. I was also told that my account would be frozen because I needed to verify my source of income since they upgraded their system but she couldn't do it because her system wasn't working. I now have to be inconvenienced yet again by standard bank again by having to take another trip to a branch to update this detail which means more ques and more waiting. I understand that systems need to be updated but DON'T inconvenience your clients along the way. I suggest you sort out your staff, It is disgusting to see that level of service delivery...Shocking!
