Change country in my Apple account

I want to change country (settings > media&purchases > view account > country region) but the system tells me to cancel ¨one or more subscription(s)¨ .. I only had appleTv for trial and cancelled as it is not for me. But the system still asks me to cancel ¨one or more subscription(s)¨ I no longer have. How do I change my country?! I travel a lot and live between several countries. How can I switch my countries?! Please help!!
