Online order not delivered as per appointment

I have a big problem with the delivery of my order *** . The appointment was set for 09h00 on 18 Dec 2020. I took a day's leave to accomplish the delivery and installation. For the rest of the day I planned different stuff. I called 08h07, 10h21, 12h15, 13h54 and 14h37 At the 10h21 call, I was told the delivery is on its way and will be soon at my door. What a big lie !!!! The other problem is that on 3 occasions I was promised that somebody would call back with feedback. Nobody called. I am extremely unhappy with the way Builders Warehouse handled me as a customer and **** to me the whole day. How are you going to fix this mess?
