If you're like me and tried the initially-hyped Jay Z-owned Tidal music service and then cancelled before the end of your free trial, you might want to check your recent credit card statements, because the music service accidentally reactivated ex-customers' accounts and falsely charged them for their services.

For those affected by the giant mistake, the full refund of $19.99 has been returned. And to make up for their inconvenience, those affected users have been given free three months access to Tidal Premium.

"We are sorry to inform you that due to an error, you have been billed 19.99$ for a TIDAL subscription. We sincerely apologize for this inconvenience, and have already refunded the amount to your account. However, it can take from 2-5 business days to show up on your credit card statement," read an email that Tidal sent out to affected customers.

"In addition to the full refund, we have also given you free access to TIDAL Premium for the next three months as a compensation."
