Inefficient service delivery

Placed order online via ASAP (Pick n Pay) on 8 September 2021. Order number ***. Received only 3 bags out 6. Driver indicated the balance will delivered shortly. Never happened. Lodged query around 3pm same day. Call centre agent took details and promised to call back. Never called. Called again around 5pm again call centre agent promised to call back. Never called. Logged complain on their app "Chat to us" plus sent email to the customer support on the same day. Received a reference number ***. Called the call centre on 9 September and was assisted by agent Shanon. She took all details and called me back giving me status. By the afternoon she indicated that the bag were located at the store and I requested delivery for today (10 September) morning. Still awaiting delivery. But received sms and email indicating the reference number supp**** has now been completed. Called the call centre again and spoke to another agent and gave her all the details and advised her that Shanon promised delivery this morning but nothing happened . She informed that she will discuss with her and call me back. Never received any calls yet. Such a poor service from a reputed retailer. I never had such problems when Bottles was used. Their complaints was handled efficiently. But as soon as ASAP took over this online app it's a disaster. Their chat to us system leaves much to be desired. More importantly I have been a loyal smart shopper customer for some time now and to get service such as this is ridiculous. These are goods that have been paid for and can you imagine bare essentials such as bread n milk included in items not delivered.
