Very Disappointed

Hi, I purchased a dishwasher via PNP Online, as there was a promotion running - receive a R300 gift voucher, dishwashing tablets, and credit to Smart Shopper card for 6 months.There were no blocks to select the voucher, and I didn't want to add tablets to trolley, as was not sure if was going to be charged for it. As this is included in the promotion, the onus is not on the consumer to ensure they receive the peripherals, as everything is part of the deal.It should be honoured by the supplier of goods.I purchased the dishwasher because of the promotion that was running, and am a regular customer of the group.
