Non-delivery of fully paid for item

It is such a pity I can't give negative star ratings as Builder's Warehouse don't even deserve the on star. I placed an order online with them last week, and paid immediately (including a hefty delivery charge), and the order on their website still says that I have paid in full and the item would be delivered on Sat 3rd March. Of course, no ballpark timeframe - merely that it would be delivered on 3rd. At about 15:00 I decided to follow up and phoned the call centre. I was then told that the item has a 60 day lead time! Not acceptable so I asked for a manger, who then proceeded to phone the branch in question and was told that they DO actually have the item in stock and would deliver it by 10:00am on Monday 5 March. Of course, I had to rearrange my day to cater for this - and lo and behold...no delivery. Late Monday afternoon i received another email expressing dismay that the item was as yet undelivered. It is now Wednesday 7th March and STILL no delivery! And no indication of what is actually going on.

Useless and will NEVER shop at Builder's Warehouse again - bring back De La Reys - they at least understood customer service
