My subscription has been canceled and the billing status is completed

Sure thing Sparkasse - I just followed up via email, so please take a look at your inbox and we'll take it from there. 

Sure, I will be waiting for the response

I see, thanks for clarifying that for me and the screenshot too Sparkasse - much appreciated.

May we reach out via email to have a further look internally at this point? 

yes it is the cirect account

check the billing also

Hi there Sparkasse - thanks for bringing this to our attention.

Can you let us know what's reported in your plan tab and your billing page at the moment and also how  you upgraded in the first place? 

Was it, for example, via the website directly or through the app store on a mobile device perhaps?

Are you sure that you're logged into the correct Dropbox account?

Any additional information is more than welcome!
