I need your guidance for my stolen domain name.

I wanted to transfer my domain name "manicman com" from Register to Godaddy and I requested the transfer code of it from Register.
Register sent me the code, but Godaddy said the transfer code of my domain name was invalid. I asked Register again on the same day and they reconfirmed that the code was correct. I decided to wait. Today, I've tried again with the same code but Godaddy says my domain name is locked.

I asked help from Register and they told me that it was transferred to
Moniker by another person. This domain name was registered on me and I never gave the transfer code to anybody, so the only explanation is that it is
stolen.

Can anyone tell me what I should do in this situation and whether there is a
legal authority to explain the situation and inform the theft of my domain
name to get it back?

Thanks for your help in advance.
