They can't estimate delivery dates and refuse to help you when they get it horribly wrong.

2nd of December: I placed an order ( # ********** 4) that had a scheduled delivery date of the 18th so I filled in my home address as I will be on leave that week. 5th of December: I receive an email saying that an item has been delayed and the order will only be delivered on the 24th. Immediately I reply asking if the delayed item can be cancelled so I can still receive the other items by the 18th when I need them. (Ticket Ref # ********** ) 6th of December: I check the tracking of the order, now it says estimated delivery 13th of December. I email back asking how to change to address to a work address as I will not be home the week that it is now scheduled. (Ticket Ref # ********** ) 8th of December: Still no response to either ticket, so I phone the call centre. A lady confirms the scheduled delivery of 13th of December and helps me change the delivery address to a work address after I explain that I will not be home the week it is scheduled as I only go on leave the following week. I did not get her name or a reference number. Immediately after hanging up I check the tracking to see if the address is updated, it now says estimated delivery 18th of December to the work address - the week I will be on leave! I call the call centre back (ref no ********** ) to tell them that on the new scheduled delivery date I will not be at the updated address, and ask if there is not a way I can schedule it for the 18th to my home address or what else I can do. I am told by someone called Jonathan that now since the address change less than 10 minutes ago the delivery has been scheduled and can no longer be changed at all ever so tough. One of the items hasn't even arrived at their warehouse yet for Pete's sake! I ask if I can speak to the lady who changed the address and he says he can see nothing on his system except my ticket on the 6th of December so this is obviously the first time I am contacting them. He refuses to even try to help me and tells me I cannot speak to a manager, so I requested that the order be cancelled and that I be refunded to my credit card and will not accept store credit. Honestly how hard can it be to stick to a scheduled delivery date? Especially if the order is early! Don't you understand that not everyone has time to sit around and wait for a courier all day? This is a problem for me every time I try to use your site, you never stick to your estimated delivery dates, not even close, and are not willing to make an effort to help customers who are inconvenienced by your lack of proper planning.
