Product: Money transfer, virtual currency, or money service

I have an account on Coinbase.com holding some crypto currency assets in their " Hosted Digital Currency Wallet ''. Coinbase decided to disable my account with no notice by any communication channel ( email, text or phone call ). I requested their support team to fix the problem with my account, and followed all the instructions they provided, and I provided them with all the information required ( copy of my ID, and a bill as proof of address ). After more than three weeks waiting, they haven't reinstated my account yet and they are ignoring my messages, they failed to provide an ETA or any information on why my account was disabled in the first place. They are holding my crypto assets and preventing me to sell them and recover the money, causing some financial harm to myself. 
So far, the timeline of my interaction with Coinbase has been : -> XXXX, XXXX XXXX : I opened a case ( # XXXX ) with their support team to get my account re-enabled. 

-> XXXX, XXXX XXXX : I received a contact requesting to upload id photo and a bill showing my address.

-> XXXX, XXXX XXXX : I received another email ( automated ) saying that my case # XXXX has been escalated, and that it would 4-5 business days.

( no response received ) -> XXXX, XXXX XXXX : I sent another email asking for the state. It's been more than a week ( 5 business days ) and got not response or update on the case.
