I ordered a xps on 21 January and didn't receive it on the estimated delivery date (24 Jan). After many follow up emails and phone call (hours of my time) it turned out the parcel was lost! Then I was told this on 1 Feb: 

"Dear Ali,
Please provide us time till tomorrow so that we can proceed with the replacement right away and it will be shipped and delivered to you in next 2-3 days once the order is placed."

I accepted the replacement offer. Now the new estimated delivery is on 13 May!!! The customer care agent who was in charge of my case isn't responding now. ​​​​​
