eBucks R2 fuel promo

For the past week I have been calling FNB eBucks section trying to find out if I do qualify for their R2 back fuel promotion if I pay using my FNB scan and pay and surprisingly I am always left hanging until I decide to cut the call because all the consultant will ask you to hold while they are finding out! Like seriously no one there knows the answer to this question I have !! Today I decided to address this using my FNB app and I was directed to eBucks help desk that said "Bankers are currently occupied ,I am number 1 in the queue at exactly 15:15 pm and now it's 15:32 and no one has bothered to assist.
