MERCYGLOBAL.CO has been reported as a fake domain registrar. They get you in by offering domains at only $1.39. Once you send them your money, you don't get a domain or response from them. Ever. 

They aren't ICAAN accredited, which means they can't even register domains. They're based out of Nigeria, home of online scamming. I also believe they used GoDaddy as a host. They've been reported and GoDaddy is currently investigating the situation. 

If you bought a domain from them, you're probably out of that money. But lesson learned! Don't purchase domains from a registrar that is not ICAAN accredited. That's the first thing you should check on.
