Random second charge, without warning.

Hey I canceled my payment 3 days ago just after I had already paid one fee but you have taken a second charge a couple hours ago. Why should I be charged again, you gave no warning about taking another charge why would you take money in the space of 3 days like that when I have a canceled subscription ? You have no way to get in contact other than robots. I purchased the subscription less than a month ago so how have you guys taken over $60 for not even a month of use ? I feel like you take money off your customers and rely on robots to hide. My rating so far is 0/10 and i will not be using this service again if this can't be sorted out. Anyone reading check to make sure these guys don't rip you off also because if they are doing it to everyone then that's theft and they will be making millions off a service that holds just over a gig of storage for me lol. All i find is more stories of dropbox ripping people off and having no hope at even getting someone from dropbox on the team.
