Worst contact centre ever

I have an FNB Account that I no longer use because the service I receive from the customer service contact centre is consistently aweful. I call to query a few things on my account I had to firstly call in 3 times because the line kept cutting when someone answered, then I speak or to. Consultant my the name of AAron Madishe. I explained my initial query and before I with security checking he advised that he couldn’t help me. I asked to speak to a team leader and he advised that there was no one on the floor to assist. I don’t know what it is but FNB you hv to do something about the service your contact centre give to people I’d like a call back and my matter resolved
