fraud by airtel

Location/place: delhi

Name of company/service: airtel

This is with reference to my number +91-9911173248 & +91-9911553248
At july 2013, I have received a call from Airtel regarding for mobile number portability to port my idea (Postpaid) number to Airtel (Postpaid).
I really want to switch to airtel because networks of idea is very poor. So i agreed to port my numbers (9911173248 & 9911553248) to airtel.
Then on same day around the executive visited my site and have taken my voter ID copy, Rs. 500 and have issued me SIM cards.
The SIM number being issued are :- 8991101302306308933 & 8991101302306308883

Airtel’s executive didnt handed me over any receipt. He just issued me one SIM card.

Now from next day onwards, I regularly got calls from your backhand regarding verifications and all but nothing is done till yet.

On 22 august I called 9810199084, this is the no. of the girl who called me before for the portablity. She told me rudely that she is at roaming and can’t talk. on other day i again called her she told me that she’ll call me back in 10 min. but still their is no response.

I have raised requests in your 121 and 198. but they are saying your status is unknown and kindly visit our airtel store.

.Till today my number status is known with Airtel. This is clear case of forgery done by that employee who has taken documents at my home. Since I dont have his information, so am quiet helpless but Airtel too is not helping me in tracking that person.

kindly help me.
thank you
