1) must use at the automated fuel dispenser (not cashier inside)
2) must fulfil minimum 10x >rm50 transaction within a calendar month (follow posting date)

Yes, 10x. So can be really 10xRM50 or 5xRM50 + 4xRM100 + 1xRM2000 or whatever. But 9xRM9000 also no use.

he meant any transaction of rm50 or above considered as 1 time, and you need minimum 10 times to qualify for the 10% cb. if you transact only 9 times, even though at a high amount (like 9k per time), will not qualify you for the 10% cb.
