Ebuck paid short by FNB for spending on 30th not qualifying

HI have been a FNB customer for over 25 years. I only got 7.5 % ebucks in November on my purchases vs 15 % as the "system" says I did not spend R2000 on my credit card. I have proof that from 1 Nov to 30 Nov 24 I spend more than R2000. I called ebucks and were told that my spending on 30 Nov 24 does not count as it will only earn ebucks when the 3rd party banks the money. My spend went off on 30 Nov 24 on my FNB card and I start paying interest on that. So why say your spending between 1st and last day will earn you ebucks if the 30th does not counts as it must be banked by the retailer ? Then say to your clients do not spend after the 25th of the month as you might lose your ebucks . I am sooooo disappointed been told this today. Just another **** by FNB trying to get clients to open accounts and then not keeping their promises. I do not care what is in the fine print Nobody reads it. Look at the dates on my credit card when money was taken off my balance.
