Thanks very much for your answer.
The problem is that, as I am at work until 7pm, I particularly given them my work address for delivery and nobody turned up there to deliver at all. On the day, I have not received it, I phoned them up and said, I paid extra for the order be delivered today but I have not received them. They than said, they re-arrange for delivery the next day. Since nothing was delivered again, I phoned every single day since then and I they kept saying, they are investigating. Until today to tell me the currier informed them that they actually delivered on the original delivery date as requested.
Although I repeatedly said I have received nothing, they insisted that they have to check the signature against my signature to determine whether it is my signature or not. I have been shopping with them for long time now and never had this problem before but it is shame to see that they are not helpful at all. All they are now saying is , until the signature has been verified that does not match with the one the currier holds, no refund will be issued.
