FNB is lying to their customers

In September FNB contacted me regarding a new Pre mier account, whereby I left my previous bank. There was a lot of promises made for which none have been met. We have made numerous calls and complaints, none of which have been resolved. Today Devashnie with a so called, managing position, contacts me by starting by saying she is not sure why the benefits has not been met, is this how one resolves complaints with noylt nlknowing yourself. This complaint will be esculated to the ombudsman. This is utter nonsense and lying to customers.
