Changing payment info in account - new credit card and new billing country

Question

Hello,
My iTunes account is set to Italy as that is the billing country of the credit card I associated with it when I started the account. Yet, I know live in Belgium and have a credit card with billing address in Belgium. I have tried to update the information but:
I cannot change the payment information from the payment information options since the address and credit card settings are set on Italy (if I try to simply type my new credit card number, I get an error message that says that the credit card number I entered is not valid for Italy)
I cannot change the Country/Region setting. The message I get is "you have an active iTunes Match subscription; you must cancel it before you can change stores".
So, does it boil down to cancelling the iTunes Match subscription? If so, how do I do it (there is no option in iTunes itself to do that)? Also, I have 4 good months left on my iTunes Match subscription - will I be credited those months back if I cancel and then re-subscribe?
Last but not least: I read some really dreadful posts from 2011 on how people who had changed billing information had lost access to their apps and were charged anew for music they had bought with the previous credit card. Has this issue been solved?
Thanks for your help!
Caterina

You have to physically be in that country as well as have a credit card (or  iTunes gift card) both of which have to have been purchased or have a billing address in the country of that iTunes store.
