Dell & Syncreon worst combo, UK

I placed my order of Alienware Aurora R13 and Alienware 610M mouse on 17th November. I was given 1st December shipping date which was unrealistic as they didn't start production of the Aurora R13 until 28 or 29th of November. My order got delayed first time. Whenever I tracked the order via webchat or call they gave me different information about why my order has been delayed. The next estimated shipping date from Dell was 11th December. Again they couldn't work in timeliness manner and delayed my order. In the meantime I contacted them as some advisor told me that they have raised a request to get the information from their production team to get transparency on why my order has been delayed. I didn't heard anything back from dell so called customer care to know that there is no such request raised for me and they were clueless about why my order was getting delayed. Finally on 14th December dell managed to ship my order but only shipped one box I.e. R13 Aurora and forgot to ship my mouse. Now the R13 is with syncreon in Lutterworth which was supposed to be delivered today on 17th December but got delayed again to 20th December because the order is missing the mouse. Syncreon doesn't know anything about the second box but dell says they shipped both R13 and the mouse on 14th December. Now nobody knows (syncreon or dell) about the missing box and hence again the order would be delayed which is ridiculous. I regret placing my order with dell and their customer care service is a joke. Dell doesn't know anything about order delay reasons what part is missing and give false information from one agent another when called them to ask about my order delay. My order is worth almost £3k and this is how dell treats their customer. Please avoid dell no matter what. I wanted my products before Christmas but this won't happen thanks to dell and syncreon.
