POOR SERVICE

i ordered a laptop on saturday the 25/02/2018 and it was soposed to be delivered today the 28th, so i checked the tracking on the item and noticed that the last update was on the 26th so i sent a request for detailed tracking as i work nightshift and sldep during the day so knowing exactly when my item all be delivered is important to me. i jus checked my tracking page now and noticed that they ordered another laptop thats now goin to be delivered on the 06/03/2018. i did not recieve an explaination or what had happened with the previous laptop as that is still showing that its going to be delivered today. im confused as to why they would order another one and not let me know why. i love shopping online and was a really good customer to them every week or second week i order from them so i expected some kind of communication. really dissapointed as i love their products but something that i need urgently i cant wait so long for.
