BAD SERVICE - DISCOUNT VOUCHER

I received a Voucher via WhatsApp R120 off on R400 spent. I went to Eastgate on Saturday the 06/06. 1. The cashier didn't know how to process it, he went ahead and did the sale, once I checked the receipt after paying I saw he didn't process voucher 2. I then asked for the purchase to be redone with the voucher, they refunded me, but when they redid it, the voucher on WhaysApp didn't have a barcode 3. they then phoned customer service however couldn't get through as they only opened at 10am.... on A saturday???? your busiest day????

How can you send vouchers to customers and waste their time like this????

I would like you to fix this, so when i go back to the store I won't be wasting time.
