Poor Customer Service with Disabled people Unprofessional

On Monday 14 September I went to their offices in Durban Smith Street, their services is very very poor bad I must say unprofessional. I'm a disabled person with poor vision, I enter the office and told them that I partially blind and I was ignored i was insulted in front of the customers. I wish their management be taught how to handle and deal with people who has disability and be trained, u can still wear glasses but have poor sight there is no need for someone to tell u that how come u got glasses on, seriously that day felt embarrased what if I fell because of no assistant. I even asked for the manager forgot her name wish if I go any time things changed.
