Pathetic customer service!!

I made an online order on Builders website, it has take more than a week and I still have not received my order. On Wednesday I received a call asking if they can deliver, but they did not arrive. On Thursday they also did not deliver, and no phonecall to me with any update/information about my order. On Friday I had to call them to find out where my order is, I was told they will come on Saturday. It's Saturday today 11.00 and still nothing arrived, I called them again only to find out that there are no trucks available to deliver on Saturdays?? They are *********** pathetic people who do not know how to deliver a service to paying customers. This is terrible customer service, I am sure that Chamberlains would not do this to customers!!
