Worst customer service

Placed an order on the 25th of November 2022. Delivery is scheduled for the 6th of December 2022. On the 4th of December 2022 on the app it indicated order was shipped however no delivery took place on the 6th of December. Phoning them to find out where my order is i get different excuses- it was not yet shipped then the order is at the branch but must still get scanned in then they split my order and indicated one item must still be shipped as it was ordered from the supplier but according to their system it is in stock. They promise to phone back to get a time and date when it will be delivered just to get an email saying they emailed the branch. I even offered to rather go and collect my order but that just gets ignored
