credit card and ebucks not linked!

I switched banks at the beginning of November 2018 to benefit from FNB's ebucks and other rewards that my other bank was just not offering me. However, I am very disillusioned now as I have been with them for 3 months and I see that I havent been accumulating my ebucks on my credit card as originally thought. When I app**** for the credit card I app**** for ebucks and both were put on my banking app and hence I thought they were linked. No one informed me that I actually have to link them myself and no one asked me when I app**** for my card if I would like them linked. Now that I have found out that I have lost out on three months of credit card purchases, I have asked for them to be back paid and I have not heard a word about whether it will or wont be done.... only that I dont have any ebucks owing to me! Not the answer I was looking for! Please can someone assist with this matter as I wont hesitate swopping to another bank then who offers better service.
