iTunes Issue

I am in the UK, however, for some reason my iTunes account has been linked to the United States and whenever i attempt to download certain apps or music is says ‘this apple ID is only for use in the UK store’. I have attempted to change my country/region, however when i try to it says i have to cancel my apple music subscription in order to do so.. which i have done, yet i am still receiving the same message which doesn’t allow me to change my region. This is really frustrating and i don’t know what else to do
