Coinbase made an unapproved withdrawal of funds ($945) from my bank account and showed NO corresponding purchase of digital currency in  my account with them.  Then, to add further cost and loss to me, they arbitrarily cancelled a purchase of Bitcoin that i made in November, but waited 6 days before advising me of the cancellation, costing me approximately $2,000 in the appreciation of Bitcoin.  They accept no reaponsibility for any of it, and they still hold my funds.  Pretty much a straight up case of theft.
