Airtel — airtel nmnp issue

Dear team, i, sanjay using airtel number [protected] had given a request to change my number from karnataka circle to kerala circle as i was transferred there. I went to the airtel store in cochin and the representative asked me to send a porting request and gave me a new sim. He told me the previous sim will get deactivated in 7 working days and i will have to continue with the new sim after that. The previous sim got deactivated on 11th jan 18 at 00:02 hrs but the new sim did not get activated. To get this resolved i visited the same store. They had no resolution and he told me he will escalate the issue and get it resolved. However it is still unresolved. I have been visiting airtel stores and calling the customer care everyday, only to be promised new timelines to resolve the issue.
I have also emailed to the airtel appellate authority and many concerned repeatedly but i have not received any response from them. I am worried if this number which i am using since 11 years will get deactivated permanently. I feel i am being harassed without any resolution from anyone in airtel.
My visit to the airtel store in cochin was so horrific that the supervisor mr anand threatened me to walk out of the store.

Please help me in this regard

Sanjay
