Disgusting service

I accompanied my mom to nedbank westgate mall, when we got there, the line was long and it was not moving, I went to a lady at reception and queried that the service was way too slow, my mom is over 60, diabetic and cannot wait on the queue for too long. When we were inside it took more than 30 minutes to be attended to, people that were before us were attended first, I asked to speak to the branch manager, which was nowhere to be found and no one was willing to speak to me, the lazy, pathetic, and unprofessional staff were there, some on their phones, some just sitting and doing nothing. The service there was just disgusting and that's an understatement, there is no point for nedbank to pay such staff. It was clear that they didn't care what was going on, another gentleman even came inside and informed staff that there is an elderly person who is on the queue outside and he asked if she can be attended first, they didn't care at all, I am not even sure if that elderly lady was attended to. Maybe nedbank has got a lot of money and do not need anymore clients if they treat people the way they do. What I saw was beyond disgusting to say the least. My mom has been a nedbank client for years, and thank God I do not bank with them, otherwise I would have immediately closed my account, and that's the same advise I gave to my mom. What I witnessed was shocking, the branch manager which I was told her name was Precious is useless...I still cannot believe that I experienced such today.
