I've paid twice to update my Dropbox account, but it's still the same and asks me to upgrade.

Thanks for letting us know about this here, in3dee!

Did you upgrade your Dropbox account directly from www.dropbox.com or did you use your Google Play/iTunes account? 

You can also attach your screenshots in this thread (just make sure there are none of your personal info showing). 

Let me know once you have more info.

my dropbox is connected to my gmail.
But i upgraded from the site, possibly i went onto the site from my gmail, donðt remeber, but i updated on the site, and filled in my creditcard number and info.

this is a screenshot of the sms from my bank. it translates to : Payment for 119,88 euros to Dropbox. confirmation code:numbers.

Hey in3dee, let me jump in here!

Do you happen to have another Dropbox account, associated with a different email address of yours?

If you have the transaction ID that is linked to your charges, you can also take a look here. Can you try this?

Keep me posted for any updates!
