We manage a not for profit and have sent them the necessary documentation showing we are a tax-exempt 501c3 in the US. This has been very embarrassing when you have people we work with asking on a weekly basis when will we provide them with more space so they can do their jobs. I cannot get anyone from Dropbox Business to upgrade our account. After several emails and phone calls, as of today, Friday, February 28th, that's it, I will be looking for another company. Very frustrated.
