I have two emails connected to one Dropbox however I seem to have been paying for two separate Dropbox accounts for years. I didn't realise until recently. I have tried every way possible to contact Dropbox but they don't seem to want to offer any support or even communication so I let one account laps in order that they might contact me but all I get is demands for payment. Does anyone know how to contact Dropbox support by email, chat or phone or do I need to send a letter?
