Error When Submitting Billing Issue Form

[lixtastic]

To my horror, today I found that I've been charged for a Dropbox Plus plan for an e-mail account I am not associated with for the past FIVE years. I have my own Dropbox, so I didn't see Dropbox charges as a red flag until the annual amount for this mystery/fraudulent one went through yesterday. My bank told me to contact Dropbox, so I filled out the billing request form (where you can email and enter the transaction IDs) twice tonight, and after filling everything out and hitting send, the site gave me an error, "there was an error with your request" and just starts me over again. Is there a direct email I can use instead of this non-functioning form? Really unhelpful.

The form is the only way I'm afraid. 

If it didnt work try using an incognito window/clearing cookies and temp internet files instead. 

Bank wont help, unfortunately, if its not a fraudulent charge (i.e. somebody cloned card)
