Taken for a fool by a bank

<p>I've been a Gold account holder with an unlimited service fee option until October 2015 when FNB called me and offered me an upgrade to Platinum. I took the offer, on the same day the upgrade was done I discovered that my account was overdrawn because FNB charged me for a new card to be issued and they charged me pro-rated service fees. This all happened without any warning from the consultant who was doing the ipgrade for me. So I immediately requested FNB to downgrade my account back to Gold. In April this year I realised there was a significant change in the service fees that I pay, FNB confirmed my fee structure was changed from unlimited option to pay as you use by the time they did an upgrade and they never changed me back to my unlimited option. I wrote to *** requesting them to change my service fee option back to my unlimited option and refund me the extra money they charged me for service fees from the time they changed my service fee option without my approval. Someone from FNB called me to acknowledge my query but confirmed that they won't be able to help me but someone will call me soon. This was more than 3 weeks ago but no one called me to resolve this.</p>
