I've tried to unlink this automatic billing but with no success. I don't even remember signing up for a Trial that turned into a PRO Plan or whatever it says. How did this even happen? Before I could figure out how to unlink this and cancel, it auto renewed!!! I was shocked to see a charge for $216.11 from Dropbox. I do not want this and I am not a business, I'm a single father of 3 boys who can not afford to have a charge for this amount withdrawn from my account, especially because I do not want it! Please help ASAP!
