You are not able to unlock it yourself and we certainly do not have access to your account to do that either. There are many reasons why an account may be Locked, but we have no idea what the case could be for you:

• Sending/Receiving Cash for a commercial transaction.
• Problem with identity verification.
• Violation of the Terms of Use.
• And many more....
