Unhappy Customer - FNB Takealot Big Day ebucks not rewarded

I recently purchased on the "FNB takealot Big Day" and was NOT allocated my ebucks rewards. When I contacted ebucks to enquire, I was informed that my ID Number was not updated on check out. I totally disagree, as this was an error I made when I did my very first FNB Takealot Big Day purchase and have since made sure that my ID Number was always captured and that my purchase was done with my Virtual Card. NOTE: Both Feb'25 and March'25 FNB Big Day rewards was not allocated. This matter needs to be escalated as I am not willing to accept this excuse. I am 100% sure that I added my ID Number.
