Online Shopping Builders warehouse nightmare

I ordered a number of items from Builders warehouse via their online shopping app on the 25/01/2021. I opted for the "collect" option as I don't live to far from the Boksburg branch and have a bakkie so collection is easy. When I arrived a week or two later to collect the items, 1. they were not ready in the collections area and I had to wait nearly an hour for the staff to go and source the items from the floor. 2. They did not have the Builders LISD924CC Corner Entry Shower - Chrome (885 x 885mm) 725902 despite there being stock when I ordered. Had they taken stock from the floor when I ordered this would not have been an issue. Further to this problem the gent working at the counter that day - Tebogo - assured me that as soon as the stock arrived they would call me, let me know and deliver at no cost due to the inconvenience. Today is the 6th of April, no call from Tebogo, or builders warehouse, no delivered shower, no update. I am surprised that there is no system to close out outstanding online shopping orders. They are happy to take your money but never delivered what was purchased.
