Disgusting service from Standard bank

I am now waiting two weeks for my money to be refunded after this bank charged me for debit orders of R55 with bank charges of R300!!! This is absolutely unacceptable and I logged a complaint with CT prestige line CONSULTANTS Morne Claasen and Gouwa who advised me they would get back to me and up till now nothing. How can a bank justify charging you a fee of R140 for a R5 debit order. I am not accepting this I want my money returned!! I got absolutely no service and yet I pay over R200 a month for a service fee .its a joke. Standard bank what happened to service ??
