I was recently offered a $1.99/month plan for 100GB while I was logged into Dropbox. Unfortuantely, I was on a plane so wasn't able to sign up in time. When I logged in later the offer didn't appear. I tried chatting to a sales agent online and they said I should have received an email which I don't remember seeing and may have gone to my spam folder. They weren't able to help and said I needed to log a ticket to get a specialist to look into this.
Unfortunately, as I am on a free account I don't have the option to log a ticket so what do I do?
