I cannot revert to the UK iTunes store

Recently, via Facebook, a Ryan Adams album was advertised with an iTunes link.

I wanted to view the album so hit the link.

I was advised that this was only viewable by changing my iTunes accounts' region, so I clicked "Ok".

There was no warning that this would not be possible to revert if you iTunes Match subscription is on, or that you can't turn it off. I am stuck in US iTunes, no use in the uk, until the end of January 2015.

Anyone able to help rectify this????

i Have already read this link:-

I can't change the country of my iTunes Store, App Store, iBooks Store, or Mac App Store account
