No Customer Service

I have now sent 4-5 emails to about 3 different email addresses to FNB and a Facebook post regarding their service and to date no one has called me. Three days later I received a message on FB requesting my details although they “typically reply within a few hours” - even after sending my details no one has called me. Yesterday I went into the Tokai branch to transfer all money out - they weren’t interested that they are losing a client - the teller was however interested in a good rating from me as she requested I rate her and not rate FNB. Why do I pay Premier rates if there is clearly no distinction!!!!
