Problem with unsubscription

Hello! 

I had a monthly subscription of Indesign which I unsubscribed the day before the autorenewal of the subsription. Then I see that Adobe tried to charge me anyway (but it didn't work since I got a new debit card and haven't updated the card on the account). How can I let them know that I wont pay that new charge since I don't even have access to Indesign anymore? I'm also currently abroad and cannot call the support directly until February. Anyone with a recommendation of what to do?

Thanks!
