Billed for FNBs mistake and poor training

I visited the slow lounge at Lanseria. Upon arrival, I asked the person behind the desk, if FNB cards qualify for free entry , as i have a premier card and private wealth card, and which should I use. He told that all cards qualify for free entry, even the fnby card for my baby. I double checked and showed him both cards again, and again he said it doesnt matter. A week later i looked at my statement and found that i was debited R250 per person, including my 2 year baby, who did nothing at the lounge. I was quite upset that someone had ****, and called the premier office, only to be told that theres nothing that they can do and i should read the Ts and Cs. I insisted on a call to be logged, and to date no response. I've been a client for many years, have all my portfolios with this bank and yet they dont seem to value my business. Im really disappointed. My private client card had 48 visits, if i had been told to check it i wouldve, but i was told that all cards qualify, surely this individual was trained in this manner, i dont see why i should pay for that mistake. That is completely unacceptable.
