Hey @Josuec09,
Do you get email receipts for your subscription purchases? Search for one of them in your email account. In it, the Spotify username you're paying for is shown:
Username/ID: xxxxxxx
If you're getting charged twice, it probably means you're paying more than one account. Checking your receipts is a way to confirm that.
Hey there you, Yeah, you! 😁 Welcome - we're glad you joined the Spotify Community! While you here, let's have a fun game…
