Unprofessional and in adequate information

I am very disappointed with builders warehouse. A few days ago I searched on the website for a washing machine adapter the saw that builders warehouse has this. I first went to Builders warehouse Glen eagles where I was told they don't have this in stock specifically (Brass fine thread tap adapter), the guy serving was kind enough to search and tell me which stores its available in. I then created an online profile and ordered from Builders warehouse Southgate because on the website it says "Stock available" the store then accepted my order and said I should pick on the 29 of March 2023. Upon arrival to collect I get told that there is no stock. No.1 I wasted bolt money to travel to Southgate why is it was I not informed earlier or called that there was no stock available!. Fine I search the site again. I see it says "Builders Kempton park, Builders Tembisa, and Builders Newmarket" have stock, to demise I find that all three stores have no stock yet on the website it clearly states that stock is available. I went as far as calling your contact center and they confirmed that at Builders Newmarket they have stock!! When I get there I'm told there's no stock and had it not been for one of the guys working in the plumbing that there is no builders that has this that means I would have yet wasted time, money and energy traveling to all builders to not find this. What infuriates me more is that clearly is shows that you guys are not doing your jobs, your falsely advertised things and saying they in stock when clearly there's no such in store. Quite disappointed in the poor service. You really suck!!
