Dont have product knowledge

I called the call centre to discuss my ebucks points, I then told him that I was told by the teller that if I have more then a certain amount in my savings pocket account I will get rewarded. He then told me I must go on the website and it will show me what I qualify for and he read it out to me. I then go on the website and it shows if I have a balance of more then R500 in my savings pocket I qualify for 2000 points which suppose to be calculated as an add on as I would have had over 9000 points. Its becoming ridiculous as to how *********** staff is working there and what about the customers that is not going on the site to see if this is true or not. Fnb are not working accordingto ttreating customers fairly. I want an explanation as to why I was misinformed and what's the way forward.
