Bad Customer Service

This is a second encounter, I had with Standard bank Maponya Mall. Their service sucks and way beyond slow. Last time I went there, I waited for more than 2 hours and left without help. Today, I waited for more than 3 hours and eventually left because it's tiring to be queuing outside, standing for many hours while they are working with their own decided pace. They might be short staffed but they just using that as an excuse not to service to fully work . They should ask Standard bank, the Glen branch for recipe because those guys are efficient. I'm tired of their snail pace.
