BUILDERS WAREHOUSE KLERKSDORP NEW PURCHASE METHOD

Been waiting on light fittings since January, no light fittings what an excuse. Been waiting on shelves since May, what a shock three items same sizes pathetic. Builders Warehouse Klerksdorp wants us to rate there product and overall service, why? I don't know what they are going to get out of it. Now they want us to purchase a product that's not even on the shelves and then then wait a week for it. Is that the last and only option to keep their clients. As a cash on order? I think personally that's not a good purchase method of all times.
