Back in January I got billed for a month of Spotify Premium Membership.  I had used the free trial, and was expecting the trial to simply end, but the membership continued and I got billed.  Shrugging it off, the same day I am billed I go online and cancel the membership for next month so that I do not get charged again.  A month later(early February) I notice membership is still active so I assume there must be something messed up, so I ignored it assuming I did not actually have Spotify premium.  However, I got billed once more today.  I cancelled my premium subscription yet still got billed.  I deem this unacceptable because I did not want to be charged at all, and now have been charged twice.  I would like some assistance please.
