FNB level 5 eBucks promotion falsely advertised and should be corrected...

So I have opened this FNB Gold account about 2 months ago, but I opened it from seeing the promotion to start at level 5 reward for 2 months and get 2 months extra for every extra product. This promotion was/is on the website. So I went to the branch and opened an Gold account and Gold credit account. But then they put me on level 1. So I called ebucks and they said that FNB handles the promotion, so she put the complaint through to FNB. They told me that if I go to tcs and c's that it will only happen if a consultant calls me. So I won't be placed on level 5 according to the ad. This is not right, as no where it stated this. It does not even state on the ad "tc's and c's apply" which must state on the ad if it does apply as in this case. The consultant at the branch was also not able to tell me that I won't get it via her, someone must call me and I specifically asked her...This should be very very clearly stated as it is very misleading. Please look into the case, rectify it and help me. As the reason for opening the account was mainly due to the promotion, now it is falsely advertised...
