Premier service suite system useless in communicating

I have been trying for 3 days to get hold of someone to help with my home loan. The s service suite is a terrible service which disconnect and transfer you the whole time and the delays are disruptive. FNB simply takes money from the flexi amount although the debit order went off on the 26th as signed and agreed when the lone was approved. To try and get an explanation is impossible. Im a premier client but the home loan is registered with wealth so I get tranferred back and forth and get disconnected every time.
