I typed in a url in error: coinbasepro.com it resolved to a page that looked like the coinbase site with an error message and a support number to call.  I called the number and the person with a foreign accent said I needed to enable the pro account by transferring money to it.  He directed me to start a remote access session and talked me through a purchase of some bitcoin.  Then he surreptitiously transferred the bit coin to a wallet that is illustrated in the attached docs.He also accessed the attached checking accounts and got more cash from them as shown in the attachments. A total of 8500.00 dollars.I realized what happened after we hung up but he had taken control of the coinbase account and completed the transfer of all the cash in it.  I called the number back but when I told him to reverse what he had done he hung up on me and now the number is out of service.
