No delivery, No responses. I will never order from them again!

Before I placed my order I asked if they were experiencing any delays in delivery. They were quick to respond and told me they are delivering. I subsequently placed my order on 11 May. Their system showed "in stock". It is now more than a week later and they have not delivered and are ignoring my emails. This item is critically important to my business so now I have to order a second one that I did not need because the first one is simply not coming and I hope I can still cancel it. Absolutely pathetic service. I will never buy from them again.
