Worst Service EVER!

Ive been a Private Wealth client at FNB for the last 3 years. After terribly poor service and a private banker I could NEVER get a hold of I decided that its not worth the money I pay every month for a non existent service. I downgraded my account to Platinum and FNB want to charge me R250-00 for a new card? This comes down to a total of R750-00 for a Cheque, Credit & Fuel card. The lady I was in connection with regarding this bluntly ignores my emails, after numerous emails she does not have the decency to answer me. Trying to speak to my previous banker is of NO help seeing hes never ever available, all you get is out of office replys and this go on in a chain of at least 4 people you have to mail before getting poor answers. I moved from Standard Bank 3 years ago to get better service as I was promised this by FNB, nevertheless, its terrible. For the amount of money Ive invested into FNB they have the odasity to charge you for new cards, would this have been the case if I ipgraded from a lower account status to lets say Private Clients, for sure not. To me its not about the cards, its about the principal pf the point. Im truly disgusted.
