Builders Warehouse Customer Service agents never call back/provide an update

Placed two orders on the 17th November 2024 as advised by the customer care agent due to one store not having the quantity of lights I required, so I did a split order. The first four lights arrived 26.11.24 a bit more than the 2 - 5 business days as stated on the order but reasonable. It is now the 06.12.24, and I was advised by the Constantiaberg Store, they did not have stock of the lights, eventhough it reflected 4 in store online however, they were expecting a shipment and that there would be a delay to my order of about a week. Fast forward to the 06.12.24, many phone calls through to the customer care agents, emails etc. no-one ever calls you back it's shocking. I have explained numerous times that if there is no stock of these lights, I will cancel the order and source other lights. I was told that the lights would arrive by this week, I still have no lights, no return phone calls from agents or the actual store. I cannot believe after a customer has chased so many times, how does Builders Warehouse not know what is going on with my order and how is it that their customer care agents are not capable of returning a phone call as I have been promised multiple times. I have been fair and patient, however, it is now at a point where this is not acceptable and I am still none the wiser and need to start the process all over again to source lights where I now only have an electrician onsite until next week Wednesday so I will now be left with to have a call out fee due to Builders Warehouse not being capable of running a decent online store, with robust customer service.
