You should have played safe once Coinbase announced that they are going to suspend deposit/withdrawal. I've say it's a bad move on your part not to take your XRP or buy more in that platform. Now they have total control of your funds, so let this be a lesson to you.
And the only one that can really help you out is to contact their support and tell them your situation. I don't know if you can get back your money or your XRP though. In any case, good luck to you.
They are FDIC insured for this sort of thing, so getting my money back shouldn’t be an issue. I just want to know if someone else has had this problem. It’s not like my account was hacked either; I hold a good amount of Ethereum and XLM on Coinbase too.
