Bad client service

I'm writing this post with disappoint Pick n Pay Pick n Pay asap! made an order on the ASAP app on 28/10/2025 at past 2pm I chose the slot for 17:30-1800, close to the time at 17:30 there was no driver that collected my order. I called their contact centre to enquire and was told there is nothing they can do I just had to wait, at that point I am at working leaving work at 18:30. I even asked them to change the slot to the next day, but still they could not do that. At 19:30 the driver called I was already home he then went back to the store and as they said he marked it as not delivered. Made atleast 4 calls to the contact centre the next day, they offered a voucher of R200 as I expressed that I am unable to wait 5 business days for my money. I tried using the voucher on the APP I then had to cancel the order due to the time the order would arrive. Today I am told that the voucher is just a once off thing, but I did not gain anything from that voucher it was redeemed on a cancelled order which makes no sense. I sent emails to customer care no response, The contact centre is useless cause they keep promising but nothing. I feel like their services and processed are useless they do not consider their clients. Still waiting for my refund funds were processed didn't gain from the voucher. Poor customer service ***
