Hi, I had cancelled my subscription but still could not take out a new one using my new country's credit card as it was locked to the old country in the payment method address. So I had to get microsoft to do it on a support chat, which was very effective and helpful. I was actually sitting in Thailand (the old country) when I did this, but the new country's card from the UK worked a day after the support chat, even though I was not in UK at that particular time.
Ahh glad that they could fix that and your IP address location (Thailand) did not prevent you from doing that.
I left Australia 9 years ago and for the past 9 years I've been topping up my Australian debit card through international money transfer only to pay subscription such as this Office 365/OneDrive and Game Pass...
And I'm tired doing that because it incurs some cost due to the transfer..
So you didn't do any extra cautionary steps by downloading all your files into your PC and letting the subs expired to be able to start a new subs with the UK card? (which possibly requires a new MS account if you didn't contact the support..)
I've asked reddit was recommended to that, but man, downloading 600 GB of data, and setting a different account and then uploading those things, no man no...
And thanks for replying to this!
