Not getting paid cashback on Healthyfoods

I am being conned of literally hundreds of Rands every month because my Discovery Healthyfoods cashback is not working. Despite several long phone-calls to Discovery card, they cannot get their act together and correct this error. I am sick of spending hours on the phone, trying to get someone to help me. <br> <br> Dealing with Discovery has, in my experience, been tantamount to dealing with the most inefficient company or parastatal in South Africa. <br> <br> I am really disappointed because I purposefully shop at Pick 'n Pay and have never received my cashback, despite swiping my credit card before and after the scanning of items. <br> <br> The cashback system is a farce and a con, in my experience.
