PnP SmartShopper not deducting discount voucher.

On Sunday, I bought a 7kg pocket of PnP potatoes from PnP Promenade.

After I left the store, I realised the voucher on my Smart Shopper App did not deduct the R7.50 discount. The voucher was loaded on to my card a while ago (I have a screenshot to prove it).

Today, 28 May 2019, I called he Smart Shopper Call Center and was after explaining in detail what has transpired, I was told always to print the vouchers in the store. Duh!!! What the purpose of having an App then. Also very often in almost all the stores, the terminal is either off line or damaged.

Then, I was politely told that I "Should Have" mentioned it to the teller so they could call in and have it sorted out. My response was that the the App "Should Have" worked then we would not be having this conversation today.

Bottom line nothing was resolved, I lost my discount of R7.50 on the purchase and the voucher expires on 29 May 2019. It's not like I buy 7kg potatoes every second day.

The call center operator was pretty clueless on how to assist me as I challenged him on every backwards suggestion he made. I'm not sure who writes their training manuals.

This is very much more than just the R7.50 I lost, but about the principle of this matter. How many customers lose out in this manner????

I expect a response from Pick n Pay on this matter.
