If you have been charged twice for a TIDAL subscription, it could be the result of two active TIDAL accounts. 

Please check to see the date of the charges. If the charges are on different dates, then this is most likely due to having a second active subscription. 

You can contact us below via the Submit a Request link. Please provide us with any email addresses that you may have used to register with TIDAL. This will help expedite the process of getting your accounts and billing straightened out.
