Update. I was on the phone to India yesterday for about an hour. Was told 2nd tier techie would call me when I chose two hour window...So I said between 9 and 11am.
Almost midday came and went with no call. I called them and was on hold for 25 minutes until agent #1 answered. I had to phonetically spell my name THREE times before he understood, it isn't difficult! A quick unproductive chat later and he said he was upgrading my call to the people who should have but hadn't called me earlier. On hikd another 30 or so minutes to be told by agent #2 that the people who shoukd have called me between 9 and 11 would do so in 30 minutes. Promise..That was 30 minutes ago. Still no call. Before hanging up he thanked me for choosing microsoft. Imagine the hollow laugh I let out. He did admit though that the recent update has inundated them with problems which is why they're late returning calls.. Who knew eh?
