FALSE PROMISES

I app**** for a credit card upgrade at FNB and received a call from a consultant, she advised that because my cheque account is platinum and I am upgrading to platinum credit card my account will be aligned as part of the upgrade for R199 and i will move up to a higher earning level on my e-bucks reward account. On 29 March 2015 I upgraded my cheque account to Platinum and was demoted to a lower earning level for the whole of that month as my credit card was not aligned. I have received my ebucks for April 2015 and my earning level is still the same and was never promoted to a higher earning level. I dont understand how FNB can promise the alignment and not fulfill the promise even though the call has been recorded.
