No way to buy partner vouchers

There is no way to spend Smart Shopper points to buy a partner voucher. When I try in the Pick n Pay app, I keep getting an error saying Pick n Pay is experiencing technical difficulties. I contacted their Customer Careline and was asked to send a screenshot of the error. I rep**** to the email with the attached screenshot. The only response I got was an email saying "Your call with reference *** Partner vouchers has been completed, we appreciate your continued support". No resolution and I still cannot buy a partner voucher.

If you go their website, it states that you can also switch your points either online or at an in-store kiosk. The website has no such option and the staff in-store had no idea what I was talking about! Pick n Pay has been dropping the ball on customer service; no wonder they are losing market share to the likes of Shoprite and Woolworths :-(
