I'm still having issues with purchasing the extended warranty.
The call back service was down but I managed to find a number on the net.
I spoke with someone in xbox support Ireland who could see the issue is that my console warranty is currently expiring on 6th February 2015.
So over 2 months later than it should be. So instead of the system seeing that you want to extend a one year with an additional 2 it's getting confused as you already have more than a year.
He's raised a ticket with support to look at modifying my account to enable me to buy it but it's only a couple of days away from the 45 day limit for purchasing so its getting silly if they don't get back to me in time.
He also couldn't tell me why it's adding 23% tax on to the £59.99 and said that I should open a ticket on the ask Microsoft website!??
This is ridiculous, I'm going around in circles with the website and unable to pay for a service and give them my money.
Not only that but no one in support is actually able to just say: hey, lets take payment over the phone for £59.99 and link the warranty to your account. They seem to be completely useless as does their website.
