I found Dropbox fine for storing files on, however their customer service is absolutely appalling. Even though I cancelled my subscription in ample time, Dropbox are continuing to charge me each month. Of course, they conveniently have no records of my transactions. It is impossible to resolve this with customer service staff. They will give you a stock answer with a lovely list of excuses which ultimately point the finger of blame at you instead of where it belongs, at them. I would avoid Dropbox at all costs! Save yourself money and time by choosing another provider.
