Trai — extortion after porting by airtel & vodafone

Address:

New Delhi, Delhi, 110025

My number was ported to airtel i. E. [protected], i paid unwanted bill of more than rs. 12, 000/- ported out to vodafone, at last call i was aware that all my pending bills were cleared, now not only at my number but also at my wife's number airtel keep calling asking more money which as per my legal knowledge after porting airtel cant, now received sms from vodafone too... It seems there is nexus between the two to grab, extort maximum money from the consumers.
I will have no choice other than to file case against both the companies.
Matter referred to trai.
Sms attached.
