Not FNB's problem

I posted a review last week about ebucks not rewarding points for a R2000 transaction that was done on 31 August. I paid online on a weekday. So I could not move up a reward level, level 5. Twice now, the feedback I got from FNB is ridiculous. Yes it was paid on the 31, but on their side processed on the 1st or 2nd Sept. So this not FNB's problem, there is nothing that they can do. I make a payment, fulfill the terms of going to level 5, the amount appears on my transaction history as well as my statement but I cant be rewarded because FNB only processed the amount 2 days later. There are also so many other small charges to my account that are taking months to sort out. FNB sort it out!
