Airtel — verification team not working as per process

I was using a airtel prepaid sim till last two weeks. My sim suddenly out of nowhere started to show no service. Went to airtel store. They said i will have to make my phone postpaid. I agreed and submitted required documents. Now they said the verification team will reach at address given. But it has been 1 full week they have not turned at the desired address giving silly reasons. My phone is off since 2 weeks now and i am helpless. Airtel should take care of this as i have been a loyal customer since almost 10 years now.
