Extremely unsatisfied with the change in ebucks rewards

Extremely unhappy with FNB and their ebucks rewards. I had a fusion account and was sitting on level 4 in terms of my ebucks. Earning a decent amount of ebucks (4000 per month) as I met the requirements set out by FNB. My fusion card expired and I was sent an aspire card because FNB decided to remove the gold fusion account. I am now on level zero and was told by the bank that the most I can earn is 400 ebucks per month which is ridiculous! I have to now get a credit card to earn ebucks which I don't want. I don't understand how these banks get away with changing accounts and systems in a way that does not benefit the client at all!
