Appalling Service Received from Pick n Pay ASAP

I placed an order on the Pick n Pay ASAP app and it was accepted at 15:22 by the store and planned delivered was said to be by 16:30. After placing the order and checking the app for updates I had seen that their had been no movement on the stores side. I then checked again closer to 16:30 and the planned delivery time had changed to 17:00. After contacting the customer online store I was placed on hold for about 20 minutes if not more by an agent that had said she is going to get back to me. After receiving no feedback I once again contacted the customer service line but have been sent from pillar to post. When the order was placed the store accepted my order and processed it. Only after contacting the customer service line I was I formed that the store was closed. I have done numerous follow ups only to be sent from pillar to post. I can't even change the store to an alternative close to me or change and order via Checkers 360 or MrD due to the fact that if I do a payout from the app to my bank account the money will only reflect after 3-5 working days.

The customer service line shows no concern and instead places me on hold all the damn time. To say that I am frustrated is an understatement
