Bad service again from my bank......

Last week Wednesday I called the call centre about debit orders I needed reversed that shouldn't have gone off my account. I spoke to Cheslin who assisted me, his system was slow , that was the first problem.Then according to him he did the reversals as requested one of R280 and one of R249, the call took a good long while and my airtime ran out and we were disconnected. I received no sms that my request was being done, a few days later I am still waiting and not happy at all. I have banked with Standard Bank more than 9 years and this service is not on par. I spent more than R40 on the call , no feedback, no funds received as requested, its just unacceptable.
