No Vitality points are being allocated, and no service to bring resolution

During the course of the year, I have repeatedly had to question why I do not receive my Discovery Miles for my Healthy Food spend. The most recent query being 2nd week September where I did not receive any points and when I asked Discovery, it was said there were no healthy foods bought in August. This is completely untrue and I even sent them some receipts I had kept. A week later I was asked to send my Checkers Xtra Savings card and Woolworths card numbers. I did this and 2 weeks later I still have not received a resolution or my points. From last week my Discovery bank is not giving points for spend goals. Discovery, there is something very wrong with your App currently. Or you are purposely not giving people their points. Unacceptable!!
