First & last time i use Builders online order service

I ordered a large quantity of lawn dressing to be delivered from Builders Warehouse Constantiaberg. The first and the last time i use their online service.

I placed my order on 28 September 2021 with a delivery date of 11 October 2021, at first i thought the wait is a bit long but i didn't need it urgently as i had some left over so i paid for the order.

Today is 15th October 2021 i have called them every day since Monday to find out where my order is as no one has bothered to pick up the phone to call me with a new delivery date.

This morning i was told they have no stock, so i have 3 questions i would like answered.

1. Why has no one bothered to call me? 2. Why are you advertising items, making customers pay for these items which you are unable to deliver? 3. When am i getting my order as i now need it urgently?
