Coinbase ripped me off for $4000 and I had dealt with them before. They stopped responding to me. Strange. They were happy to respond when i had other questions.
I know I'm not the only one. I told my bank what happened, and my bank got me back 2000. It's not enough but it is something. I would love to see a class action lawsuit against them. For those of you that love coinbase just watch what's going to happen to you. Don't use their freaking service anymore!!!!!
I'd be careful with that, they can likely debit your bank account again and/or file a fraud report with the police for reversing a transaction you did authorize.
I told my bank what happened, that they allowed 1st transaction to go through and then proceeded to cancel the following 3/also putting my money at limbo for awhile. This was when bitcoin went from 200 to the moon. I told my bank about what happened and they advised me to file a report/claim and close the account.
