Missleading a customer

I changed banks in 2012/2013 and moved to Standard bank. I openned a Prestige account with Standard bank and I was told that one of the benefits of this account was U- count rewards that i will get everytime i am using my card. I had 2 credit cards with Standard bank and decided to pay off and close one credit card in January this year ( 2019 ). So last weekend i received a call from Standard bank card division and, I was told that, I am owing R500 on the card that I close. I thought it was a ***** and I said to the lady, I will go to the branch and found out about this.

So I called Standard bank credit card division myself. To my suprise, It was true I was told that i do owe Standard bank. Apparently I was paying every month for having U-counts reward and it was charged on my credit card, now that I have closed the card its a problem.

What make me unhappy about all this is,,,,, I was told its a benefit given to me for having this account with them, nobody said I was going to be paying a fee every month. If that is not misleading a customer into buying something with you and promising lies ( Then I dont know what it is ). IF I knew i was going to pay a fee, I was not going to agree. I AM VERY DISSAPOINTED IN THE WAY STANDARD BANK IS DOING BUSINESS. HOW CAN WE TRUST THEM WITH OUR MONEY IF THEY CANT BE HONEST WITH THINGS LIKE THIS.
