Airtel — ported number deactivated and neither airtel store nor customer care takes responsibility

Address:

Bangalore, Karnataka, 560067

My airtel number was of delhi circle and i requested for porting to karnataka circle on 3rd march 2018. They did aadhar verification also. I received the confirmation message on the 8th march. At 10pm my old sim was deactivated and new sim did not work. It said 'network not available'.
After this, i made so so many calls to customer care and they said they had no information regarding this number n i should contact the airtel store where i had forwarded the request.
I went again to the store to get my sim activated. They gave me a new sim n said it will be activated in next two days. They have applied for processing! And when i check with customer care, they still have no information!! And want me to re visit the store. And when i check with store, they have no response received yet from the back end.

Where do i go now?! That number of mine is the registered number at all legal places and my day to day life is stuck!!
I escalated the matter to higher official too.. But no response still!!
