FNB Private clients - what they DONT tell you

I decided to upgrade a week ago from FNB Platinum to Private Clients. But what they didnt tell me is that I will lose my eBucks reward level for a month AFTER UPGRADING (seems like a downgrade then?). Today I tried using their advertised benefit to book an airport transfer (as offered in their terms and conditions, which applies to my current ebucks reward level). But because their internal systems are not synchronised between banking and ebucks for my account upgrade, they want me to wait a month before I can use any of those services. This seems very unfair to me and is misleading in my opinion. If my eBucks reward level is currently 3 (as displayed online) and my account says I am currently a Private Client (which it does), then I should qualify for the airport transfer as per their terms. If this complaint doesnt work, then the Banking Ombudsman & ASA will both hear from me next, because this is unfair and misleading advertising.
