Someone stole my business name! Help? Advice?

[Lawson Ott]

Ok so I've had Easy Homes LLC for a couple years now. I advertise in my local area, Indiana.

However, I'm getting a lot of buyer leads from people in Alabama, North Carolina, and other places. 

I wish I had some houses in those areas to sell to them. 

Come to find out, they are using my business name. 

Whereas my website is www.easyhomes.us

They have bandit signs and other ads leading to www.easyhomes.today

Not sure what to think of this. how to use it to my advantage . if I'm being looted. 

Looking at both sites with different phone numbers and emails I wonder how people in those markets are getting to my site. and if the reverse is happening too.

Should I Sue? should I sell them my business  name and use the money to ramp up my business under a new better name? 

What would you do if it were your business name?
