Worst customer service and still no answer from anyone at FNB

How is it possible that I was able to make a transfer, my debit order was successfully debited and I was able to make a purchase when your call center advised that my Salary was returned to my employer? When I press your agents to advise how this is possible they cannot give a straight answer and drops the call. When you ask to speak to a team leader the agent (Dominique Radebe) advised that the all the team leaders were on lunch. When I asked again for a team leader or manager he told me that the team leader was in a meeting but was then able to transfer me to the team leader a few minutes later. This is the worst customer service experience I have ever had.
