Micromax Canvas 2 A110 — extremely bad service

I gave my phone to micromax serving center because it was dead and not working. They gave me time of 1 week to repair it. After 1 week they couldn't repair it. After the time of 1month they still couldn't able to repair it. They are saying that company is not making new motherboards for the phone so they couldn't repairing it. So begged them to give my phone as it is. Now my phone is still dead and neither of any service center of micromax able to repair it..so what i do now with the dead .phone. i cant tolerate such bad service from micromax.
