Airtel — haven't received airtel new sim after port

Address: 533001

I have submitted documents for port out from idea postpaid to airtel postpaid.
The port was succesful yesterday and the idea service was terminated. But the dealer haven't provided me a new airtel sim which he promised to deliver at my address by post. I suspect that sim was misplaced at their end. Interuption of service of this number was taking toll on my work contacts.
Following are the details

Mobile number :[protected]
Port request submission date :13/11/2017
Upc code : ia226585

Provide me a solution to get my number (New sim) which was ported to airtel.

Thanks
