I paid for next day delivery and hadn't realised that you did not deliver on Sundays. My fault I waited in all day Sunday. Waited in all day Monday and still no lights. Rang the company and had to ask for my next day delivery fee back, it wasn't volunteered. Waited in all day Tuesday for it to arrived late afternoon without the bulbs I had paid for. Rang the office twice more and was told the bulbs were in a different courier service and would be with me the next day. Another day of waiting in. The office were very rude and off hand with me. I can't even tell if it works yet. Very unhappy with the customer service and delivery. The tracking number appears invalid on courier web site. That will be 4 days waiting for a lamp that is supposed to be next day delivery (albeit one was my mistake)
