When this happened you should have received a prorated refund for the time remaining on your account. In doing so, you merged your account into hers, effectively making her the owner of the account. What you received was an invitation to join your colleague's business team account not just a folder. I received an email from a colleague inviting me to join a folder (according to my understanding) I would like to return to my original paid plan account that I already paid for one year ahead and that has all my folders and files.

My colleague removed me and also cancelled her business plan (still in trial mode) as she realised it’s not what she needed and would cause problems like this.I asked for help in the Dropbox support chat and was told that I should ask my colleague to remove me.When I joined, I found that suddenly all my files were under her name and apparently it is a business account.
