eBucks rewards

I bought tickets with FNB through their bus application, called, eBucks reflects between the 8th and 12th the following month, no eBucks, called no sir, we will contact Intercape why doesn't it reflect on the transaction as Intercape. They call back again no sir Intercape said something. Now me angry, I am not talking to Intercape I am talking to my bank.... The bank hold for me sir, waited 20 min, or sorry sir you don't qualify after 2 months of waiting. Now the bank said, your reward level is too low that's why you don't qualify, however there is no more rewarding levels since July clearly bank doesn't know their own. Went to check do I qualify according to bank check on the website, so I did and show no difference an exactly what I said..... What do I do and I wat to claim all my unclaimed eBucks that unfairly was not given of the years. This happens all the time with some PPL and even I would've left it. But they just refused my eBucks like that made me furious. Help what can I do... Calling them didn't help
