wors customer services ever

I would like to know how does ANY other Pick n Pay accept coupon vouchers and redeem it except the Mokopane branch in Limpopo. Its the most *********** staff. And it seems like they've got 20 managers. I payed almost R500 and couldn't use the coupons. Voucher number *** . It must be the worst branch in the country. Checkers Mokopane is much better. To me it's not about the money but the principal .. why offer something to your customers but don't know how it works. Im so disappointed in this branch. If the staff is not chatting or busy ignoring you the are rude .
