Airtel — no network on ported sim

I have ported my number [protected] from tata docomo to airtel. But there is no signal in that sim and my old number has stopped already. I am loosing my business calls and i am going to consumer forum against it.
This is such a bad service for postpaid users like us. We wholly depend on our phone.

Your associates keep bugging us about your plans and finally when we try it we have to face this. I urge you to start my number immediately
