My Trademark (Unregistered) is used by other party without consent

I was owning a fast food restaurant at Thane , I trade marked it with (KHAO GALLI ) under class 43. I ran it for 2 years and then decided to sell the business. Since premise was on rent, I got a buyer and introduced him to the owner. They agreed for the new agreement and I cancelled my agreement. New owner now has active agreement for that premise with different name (not Khao Galli) , however they are still using my trade name "KHAO GALLI". We had agreed that I will sign business agreement with them to transfer all rights,but same is still not done, and now they have started renegotiatig deal value which is unfair. What happens now ? Can I complain against them as Trademark is still on my name , even though they have rental agreement with other name ? Also can I set up restaurant at other place without their legal issues , since trade mark is still on my name? Note- Trade mark currently shows online as Objected , as there was a query few months back,but already submitted legal reply
