Hey thanks for the answers guys.
I've phoned three times now and I'm dreading the phone bill because it is an 0800 number. I obviously take the blame for not keeping a record of the password and then the email subsequently becoming obsolete but this was from years an years ago, I've been a loyal customer since the original Xbox was first released.
The second lady on the phone told me if I brought some Microsoft points and uploaded them onto my console then I could place the last 5 digits onto the customer support form and they could then verify that it is my account. I did this and it came back as failed again. I phoned again and all the advice given to me was basically hounding me for mine and my families details. There is no bank account details activated on my 360 and it is plainly obvious that it is my account and all I want to do is switch my windows live ID so that I could have my gamertag on my phone.
I'm sorry but the service is appalling and fishing for all my and my families details to get the account switched over is embarrassing. You don't need my credit card number to show that I have just activated points on my account and I said from the beginning that I didn't put my account details on there. This is supposed to be Microsoft, I've really lost support for you guys and I might just take back my phone and sell my 360- 40 000+ gamer points down the drain.
