Premier Banking Service Is Appalling

FNB premier banking has the worst possible service available. I had a request to negotiate the interest rate on my revolving loan. The new rate was approved but I got no feedback from the so called "PREMIER" consultants. After calling in the third time, they said that the credit manager has to call me to finalise it. I waited and got no response. After calling back to follow up, all they tell me is "the matter has been escalated". It has been more than a week now and this has still not been resolved. The best part of it is when you request to speak to the manager, they tell you its not possible. Today they told me the matter has been escalated further after holding on for more than 20min. Until now, there still has been no call which tells me that nobody cares......
