Airtel — Airtel deliberately delaying and rejecting the porting request

Address:

Maharashtra

I've submitted Number Portability Request in order to switch ([protected]) to Idea network. I've been getting reasons from Idea that Airtel is giving non-sense reasons just to delay the NMP process evenafter paying the dues. I've generated Portability code multiple times, but still no success. I know Airtel is losing 5 years old customer but they should have thought of this earlier when I raised concerns over network coverage 100s of times. Just now I've receveid an SMS from Airtel saying "Kindly sms CPR to 51619 to cancel the porting request.>Is there any way we can lodge a formal complaint against Airtel thru TRAI etc... ? please advise.-
