Hi @Amantedocha Sorry to hear this, I definitely understand your frustration.
As @AlyssaPandora mentioned, it sounds like you have more than one Pandora account. In addition to that, it also sounds like your subscription has been transferred from one Pandora account to another Pandora account through Google Play. This may be the reason why your playlists are missing.
I've gone ahead and requested that our support team reach out to you to offer further assist with this. Please be on the look out for an email from them.
For more information on why or how subscriptions can transfer, please view our Help Page here.
Thanks again for posting to community!
