did he say he is from Global?  
I have been doing payments with them out of the number 888-835-5482, told me the say thing. :(

This guy is a total nitwit.  First he says you've been served, then wants your address to serve you.  That makes no sense on many levels.  Firstly, you cannot be served over the phone.  Secondly, real process servers do not call ahead to give advance notice that they are coming.  Thirdly, they would already have your address.  Do not give them any infomation! It is not up to you to aid them with their skip tracing efforts.  Sounds like you saw through his scam right away!  Hopefully he will realize this and not bother to call you back.

Received a call from 270-847-4736 gave name Kevin Long and told me I have been officially served.  Gave me a claim number and a telephone number to contact 888-835-5482. Wanted my address so they could officially serve me with papers.  I told him I was reporting this to my local sheriff's department and if it were for real they know where I live.
