I doubt to name a Coinbase a legit company. There is no way to contact company. The phone number they advertise directs you to a website where you can explain your problem. After that you may get email from no-reply-support with a text not related to you. The text may specify an email address for communication that either not in service any more (security) or directs you back to the website to submit a ticket (help).I lost all my money to a fraudster with Coinbase. I repeat: Fraudster with Coinbase.
