Hey@waldojvl and welcome to the Spotify Community!
If you get in contact with Spotify support, you should be able to provide them with your credit info so that they can cancel your Premium subscription or even give you access to your account back. The easiest way to contact them is by messagingSpotifyCaresonFacebook, Twitter or contact Spotify Consumer Support filling this anonymous contact form. You will need to answer some questions to confirm your identity.
Let me know how it works!
Have a nice day :)
