Builders attempt at Customer Service feedback

So, after posting on Hello Peter my complaint about Builders Warehouse, I receive a phone call explaining to me that there is nothing wrong with the Gazebo that I bought and that I was at fault. This after I had shown the manager, Richard Mabasa what the default was and challenged him to erect the Gazebo in front of his staff. He would not and offered me my money back, which I gladly took as I will not be setting foot back in Builders. In my opinion, Richard is just one indication as to why the service levels in Builders is so shocking. The customer service person did not even bother to investigate properly as she then told me she would tell Richard to erect the Gazebo. Why bother? You have already told a customer that he is an idiot, without properly investigating the matter. Shame on you.
