Builders Warehouse Boksburg - Worst Customer Service!!!!

On the 23rd July 2020, I went to Builders Warehouse Boksburg and bought custom sized blinds. The collection date was supposed to be 03 August 2020. Till today I am still waiting for my order. The online status shows that the blinds are ready for collection but when I go to collect I am told the supplier has not delivered, it's been 4 weeks since I placed the order, and when I request to cancel the order to get a refund I am told the blinds are already manufactured and they are just waiting for delivery, weeks have gone by and I am still waiting. Builders Warehouse Boksburg has a pathetic customer service, never buy blinds from them
