Changed delivery time and day without communication

Pick n pay ASAP you continue to disappoint me each time I use your services!! Tell me how do you change the delivery time and date without notifying me?? When I initially placed an order at 15:56pm the delivery time was 16:30 -17:00pm and it changed to 17:00pm luckily I took a screenshot this time around. The next thing when I track my order I see time has now changed to the following day at 8-9am😡 Make it make sense please!!! If I knew this prior I wouldn't have proceeded to place the order, I mean I wanted some of the items for dinner! It's now 17:37 So tell me what should happen?? I tried calling your support center and I held in for a good 15 minutes without going through!! No information on your operating hours so one just have to hold on hoping that someone will answer😳 I also hate the fact that my money will still take forever to be refunded. I am so done with Pick n Pay ASAP!! I AM NOT HAPPY AT ALL!!!!
