It sounds like you have multiple accounts with subscriptions running on them (possibly unknowningly). If you get in touch with the customer services team directly using the online contact form they will be able to get this straightened out for you.
If you get an automated email reply back directing you to the community or help pages, you need to reply directly to that email (even if its from no-reply) and one of the customer services agents will get back to you as soon as possible.
I signed up for the free trial and canceled 25 days later. I made sure I reached the confermation page when canceling. I went along thinking everything was fine but became suspicious when I accidentally clicked a song and it played. I thought there might be a malfunction in my app and ignored it. Then I got an unexpected charge and it sent my checking account into overdraft. I went back through my account and saw this was the SECOND charge! I sent in the online form 4 days ago and have not received anything more than a copy of my form.
There has to be legal action that the many many customers who are going through this can take. I asked my bank and they said that there is a stop payment fee in order to get my money back and I would break even, which is not even, since that is MY money. I want my money and I am so sad to see all of these posts in the community that are the same as mine.
