Hi there @Intense0ne, thanks for checking in with us on the Dropbox Community.
If you used your mobile device to get a Dropbox subscription, you've upgraded via the App Store (iOS) or Google Play (Android), depending on your device type. For this reason, you'll have to contact them as they may have more info on the matter.
In the meantime, if you have any other questions, just give me a shout. Cheers!
