Builders Warehouse - false promises and lies

About 3 years ago I purchased a Trimtech 2800w vacuum/blower from Builders Express, Robindale. The dust bad has perished so I went to my local Builders Express to buy a replacement. This was about 4 weeks ago and I was told at the information desk that stock would arrive "next week". Next week came and went - every time the same story: No stock, but arriving next week. I went onto their website which provides details of stock availability and this indicated that there was one unit available at Builders, River road, Bryanston . I drove there - a distance of about 10km - guess what? NO STOCK! In the meanwhile I had made contact with Builders' complaints department and someone called Inshaaf informed me that stock would be arriving at Robindale - yes, you guessed it, next week. In fact, he was more specific and promised me that stock would arrive on the Tuesday and that he had arranged for the store manager to phone me to confirm arrival. Tuesday came and went - no phone call - so I drove there and, predictably, no stock. It is absolutely deplorable that they can sell an item and then not ensure availability of consumable spares. Maybe part of the blame lies with Trimtech as well, but that is a matter between them and Builders and not the concern of a customer. I have vowed to never set foot in a Builders store ever again and will certainly not purchase any Trimtech product.
