Discovery Vitality healthy foods fail

I have been trying since January to have an issue resolved with Discovery Vitality. Discovery has a system whereby you earn points for healthy food purchased as Woolworths or Pick n Pay. According to your healthy grocery points, Vitality pays you back a portion of your spend. However, if you buy items deemed unhealthy, your pay-back is reduced.

Items that I have not purchased are showing up on my Discovery Woolworths spend, which means I am being penalized both in points and in money. The items are not just random items but whole shopping baskets that I have not purchased i.e shopping baskets appear under my name even when I have not been shopping. For example I was in a town over the festive season with no Woolworths and Discovery has logged that I shopped there and bought unhealthy items. There are dozens of incorrect whole shopping trips under my name!

I have logged numerous calls with the call center, spending hours on the phone- again at my expense- being told over and over again that it is being investigated but to no avail. No one ever gets back to me, I must call and explain the problem over and over again! There seems to be no escalation process and no one to speak to that can actually help.

I am incredibly frustrated and do not know where to turn for help to get this sorted out!
