First time customer - NEVER AGAIN!

I am urging you to avoid this company like the plague. I used them for the very first time yesterday. Went into the store to order tile cutters. I was told to pay and that they would arrive on Sunday (today). I asked them twice if they were arriving today and twice they said yes. The reason I sought this reassurance is that companies often lie about the arrival days of their products to induce you to buy them. This is what ScrewFix did to me.
I phoned up and spoke to this horrifically rude man who acted as if Screwfix did not need customers. He insinuated that I knew that the product was arriving Monday - untrue. I was told it was arriving on Sunday - I needed it on Sunday. I was then told that because it was ordered at 5.30pm, it would not have arrived until Monday. I asked why two assistants - a deputy manager and a shop assistant had not told me this. He said "mistakes can be made" - what by two people - one of whom is a manager?
I then said I was going into a shop for a refund. He said they would not give me one until the product had arrived. So, I have no product - they have my money. I no longer want the product as I cannot deal with a company like this - and they will not refund me. A very simple process. All they have to do is refund me and cancel off the order, but they refuse to do so.
There is a very good reason why the reviews for this company are so low, not just on this site but on many other review sites. There are so many other companies to choose from - give this company a very wide berth. They treat customers as if they are expendable and maybe when they start to lose them, they will realise that they need a serious attitude transplant!
