Issue with Woolworths My Difference Program

Dear Woolworths I am so disappointed with your new rewards program. While you were initiating the program none of my purchases pulled through to Discovery. This was for april may and june. So i have not received my vitality cashback for those three months. Which usually amounts to around 200 rand per month. Discovery asked me to retrieve Till slips and when i requested this i was told that you can supply me with transaction dates and tht i need to go to each store myself to retrieve the till slips. I live in Gauteng and purchased in Durban in April. Do you really expect me to travel to each store when the issue was on your side. Further to this there’s an issue with my profile which i called about almost a week ago. To date i havent received email feedback so I actually can even access the new app. Should i now change stores where i purchase my healthyfood because of this????
