I can't upgrade via the Google Play store.

Paid via Google play store.  Don't ask me how that happened, I think I just added it as a payment method as I have had DROPBOX before the google playstore payment method was added so somehow my account has switched to Google Play store.  I spent a ridiculous amount of time online with an agent who should have been able to tell me that I can't upgrade immediately.  

I was told to:

a)  cancel Dropbox in Google Play

b)  don't worry about losing my info on dropbox

c)  wait until the end of my billing cycle when it drops back down to basic which is an obvious concern as I am worried I will lose info that is over and above the basic level

d)  sign up again sometime down the road via DROPBOX

Surely you have a seamless way to change from Google Play to dropbox itself?  Surely I don't have to set my calendar to remember the exact day and time my Google subscription ends so I can sign up again?  If I have to wait until my plan expires and my storage is over basic how can I be sure I am not going to lose my info or be compromised!

I sincerely hope DROPBBOX finds a seamless way to resolve this so that users who find out the hard way that they are on a "one way street" via DROPBOX Google Playstore can switch effortlessly!  If not, they should be flagged in big letters not in tiny fine print (if its there) on page 80 of a user contract.
