Very poor customer service

I am absolutely disgusted by the decision of FNB to downgrade the services offered to Platinum customers who had a personal banker. I emailed my personal banker 2 weeks ago, only to be informed by him that he had now moved to Private Banking and that I now reverted back to the Premier Suite. This is apparently because FNB has changed it's income criteria for private banking. I don't understand why a service which I have enjoyed for more than 2 years has been downgraded. I can appreciate for new accounts but definitely not for existing accounts. Service from the Premier Suite is sadly lacking and far too slow. I was told on Thursday that my complaint would be escalated after speaking to two people who knew nothing about me or my business. To date ... nothing. I would like to speak to someone who can actually make a decision and not someone spouting scripted 'so sorry but these are the rules'. Very, Very unhappy customer!!
