Cancel iTunes Match immediately - not just let lapse

I've just moved back to Australia and need to change the billing country on my AppleID.

When I attempt to do this, I'm told I need to cancel my Itunes Match subscription. I've done this but it only "expires" in November 2020. This appears to be preventing me from changing my country for another 7 months.

Any way I can cancel immediately? Vs, letting it expire over time?

Many thanks.
