Locked accounts usually don't get any replies. I honestly don't think you can get $1200 back. Of course, you have to try your luck to the fullest. Hope you can get your money back.
If that's the case to all then how can they prove that the locking of an account was just a mistake? I don't think you can't get any reply at all if you're account was locked probably it will just take time until they respond to you and asked for the details. By the way, I guess OPs issue isn't about being locked, it's likely been on hold until he proves that it's legit on his side.
