Airtel — After port the new SIM is not working

Address:

VILL RAJBANSHI PARA, PO SRIPUR BAZAR

Hi, it is almost past two days and I am unable to use my mobile number which is playing very important role to my life. I got a text stating that after 11 PM my new SIM (Airtel) will start working, kindly replace the SIM and restart your phone. I have done the same but till now there is no network sign for my new Airtel SIM.

Kindly help me, it is really important to me. Thanks in advance.
