If you're seeing two charges from Spotify on your account it could be for a number of reasons.
First, check with your family or friends to make sure someone you know didn’t subscribe with your details.
There are a few reasons why you might see two charges in one month:
Are the charges on two different days? Then you're probably paying for more than one account. We’d recommend checking our support site to learn how to find and cancel any other accounts.
The payment was unsuccessful, but appeared on your statement anyway. If we’re unable to process the payment, the funds will reappear on your statement soon. This is all part of your bank/credit card’s authorization process. You can reach out to them for more information. You may see multiple charges like this if you tried the payment multiple times.
If you’ve recently upgraded from Premium to Premium for Family your renewal date may come earlier than usual, possibly in the same month as your previous payment. This is because of the price difference between the two subscriptions. You can check your Premium renewal date on your Subscription Page.
If you think your details have been used without authorization, please read this FAQ.
