This is the third time I have cancelled Plus and I keep getting charged.

In 2023 I changed job and the new system would not allow dropbox. 

I cancelled the Dropbox Plus, and deleted all but a few files 

The next year, I got charged for the Dropbox Plus. i never used the Dropbox in that year. 

I went back and cancelled. 

Never used it

The next year got charged. 

Went in and cancelled. 

I just got charged again. 

I went into the Management and cancelled - there are a LOT of clicks needed to cancel. The thing says I'm now scheduled for cancellation in a year. 

No I want a refund and Cancel NOW. Where is that button. 

This is impressive design to extract maximum money by stealth.
