They wont let you cancel it.
This is a problem if you move countries as you cant swithc stores while your subscription is running.
you cant buy anything or download anything.
Your credit cards wont work because you will be defaulted to the address system of the country I tunes match sub was in.
I moved to the UK from the US
for billing adress it asked for a US zip
I dont have a US zip
I have a UK zip which the US store rejects
same with phone numbers
Nothing works because of Itunes match as you cant change countries until the subscription runs out...then you lose access to everything you bought in the original store.
Think you bought all those songs?
YOU JUST HAVE A LICENSE FOR THE COUNTRY YOU BOUGHT THEM IN.
MOVE AND YOU NO LONGER HAVE A LICENSE
Call your credit card company and dispute the charges after they are incurred and file a complaint with the BBB. Maybe Apple will wake up. http://www.bbb.org/sanjose/business-reviews/computers-dealers/apple-computer-in- cupertino-ca-198239
