Pinecrest Nedbank poor service

Today I went to nedbank pinetown pinecrest branch just to change the my cell phone service provider number for OTP reasons, I was not able to do it over the phone and was told it take few minutes at the info desk. I rushed and got in just before they closed, and could see the info lady did not want help and then gave me a ticket to wait for avail teller, they where very quite , but being a Friday it looks like nobody wanted to help I could hear a gossip abt giving me a ticket when it almost closing time, I was then told the system was offline, without knowing what I needed, I feel the service is very poor and unhelpful, I'm actually going to close my account, that's not how people should be treated
