Poor service

The service I’m receiving from nedbank as new client it’s very bad , I can’t access my banking network profile as my cellphone was captured incorrectly and I was told by the call center to go to the branch to update my cell, I took my time for my lunch to go to jabulani Mall nedbank the service there was very bad I waited for and hour on the line that didn’t move the was about 15 people on the line I was very suprised a big bank like Nedbank can’t service few people everyone in the line was complaining about the service I even exceeded my lunch and didn’t get assistance I’m very sad to see such
