Rewards Vouchers offered, never delivered

I received an offer from FNB to spend a certain amount before a certain date in December, and receive cash back vouchers. I spent more than the required amount, and received nothing.<br> <br> I have already sent in two complaints online, and called last week when I received no feedback, to be told that I would hear back from them regarding this within the same day.<br> <br> Still nothing.<br> <br> This is not the service I have come to expect from FNB. <br> <br> I am highly disappointed, and feeling cheated. <br> <br> Following a further lack of feedback, I am likely to submit a complaint to head office about the person involved, who holds a good position, and promised feedback.<br> <br> <br> <br> <br>
