Terrible service

I placed an order on Pick n pay clothing website and my order was given to DPD/DAWN WING COURIERS. They sent an sms to say my parcel will be delivered on the 25th May 2023 but that didn't happen and I just got an sms to say they couldn't deliver with no valid reason. Next going I check on the website, it says they couldn't deliver because they couldn't locate the address so someone from customer care will call me. The 26th May 2023 I received another sms to say they will deliver on that day. Unfortunately I wasn't going to stop everything like the day before then they don't deliver. When the driver called, I told him I'm not available. The next thing I get an sms that my parcel has been delivered and signed for by security. Who the hell gave authority for such? For hygiene and security purposes, I will not accept that delivery. Your driver can go get it from that security he gave it to and return to Pick n pay as I want my money back!!!
