I bought a SP1 back when the SP2 came out, and over these past holidays bought a SP3. Gave my sister the SP1 and ended up taking the SP3 back as it didn't quite meet my needs, especially considering the price paid. Very premium price, very premium gear! All was good up to that point. But I had bought Microsoft Complete for the SP3 since these things are essentially non-repairable. Bought the coverage on 1/2/2015. But I've returned the SP3 to the seller and went to cancel the MS Complete coverage according to their terms. That's where the trouble began. I have the receipt, gave them the contract number, but they needed the transaction number. That isn't on the receipt. They said it would have been in the email when I purchased. Problem is there isn't such an email. Not with the MS Complete for the SP3 nor with the one I bought for the SP1. So basically I was told in nice terms to go punt! So punt I did! Reversed at the CC company, now we'll see what happens next. Here's the rant. For a highly premium product like the SP's, the support structure should be every bit as good as the equipment. That just is not the case with MS. Offshore support of a poor quality is the norm unfortunately. I won't be buying any more MS branded hardware going forward. The other premium product out there is Apple. And support with AppleCare is head and shoulders so far ahead of MS that it isn't fair to speak their name in the same sentence!
