I'm not sure if your card will be disconnected from your account if you deleted it without canceling subscription. I've seen some posts here on community from people who were still being charged after that. I'm not sure if it was by mistake or that's just how it works.
That's why I recommended contacting Spotify directly, just to make sure your card is removed and you won't be charged. If it isn't, they will disconnect it for you.
Hi again and sorry again for bothering but i just forgot to say i had 30 days trial for first time and now this day i wanted to remove my card but i cant see an option with change or cancel so i think my credit card is removed.
