Account upgrades and Ebucks

My experience with FNB has been very bad the last few months. It all started in November when the call centre phoned me and convinced me to upgrade my Gold account to a Platinum account. The representative did assured me that it is the right choice to upgrade. However he did not mention that the criteria for Ebucks will change. With my Gold account my Ebucks earn rate was at 15% and after the upgrade it was lowered to 5% because I do not meet some of the new Ebucks earn requirements. I went to my branch in Bloemfontein and they said I must give it another month to see if it remains the same, it did. I phoned the call centre to revert all changes to my account to go back to the Gold account again as it was. The representative said that he will be able to revert it back to a Gold account but the credit card I must do myself. Up till now I haven't even received a SMS with a reference number. FNB must revert all changes to my account to exactly the same as before the upgrade.
