Misleading adverti*****t

I saw an advert for aspire black fnb card for 59 rands a month, saying you can earn ebucks, I upgraded, and now I am not earning ebucks, when I enquired, I am told I must have a gold cheque card and gold credit card, on the adverti*****t there was no such information, FNB is very misleading , be careful guys, they are doing business on our expense
