Are you able to call Go Daddy?
Is your locked domain current (active) (paid?) -- or has it expired?
With the details you have provided, it is difficult to know what the problem is, however if it were me, I would call them ... send money if necessary. If the domain has expired, you may need to pay a Redemption Fee.
Make a list of the questions you want to ask before you call, so you can ask all the necessary questions.
If there is something you don't understand, instead of repeating the question, try to ask the question again, but in a different way.
If need be, ask to escalate the phone call, and speak to a supervisor. Get a Support Ticket issued, and record the number. If you need to follow up further, you will have a "support ticket number" to reference in your email or phone call -- all of which can make things easier.
Good luck, and let us know how things work out!
