Fnb Service non-delivery

Phoned this morning {02/08/2018} to query a debit order issue. I tried to explain the matter to the lady named Emily, but was constantly interrupted. After explaining several times she saw the problem. I was put on hold but unfortunately I disconnected the call after 15 minutes of waiting. I tried calling two more times and waited 8 and 10 minutes. I called in the PM, and the call was answered immediately by a male consultant. I explained my situation and asked to speak to a manager. He said he will put me through and put the call on mute..... And again, I had to disconnect after nobody responded after 5 minutes of waiting. It is totally unacceptable and very unprofessional service.
