Consumer Redressal

From 02nd August 2015 my Airtel 4g wifispot Datamax 01 datacard with power backup is not getting network. I have taken Airtel 4g Rs.999/- (plus tax as applicable) plan in which as par Airtel commitment they are giving 10GB high speed internet and after consumption of 10GB high speed internet it will be low speed internet. My Airtel 4g datacard number is 8585880331.But after my 10GB high speed internet exausted on 02nd August 2015 morning Airtel India barred my datacard num 8585880331 from accessing there network. I complain them almost everyday by calling there customer care number and mailing them on there email addrees after I stopped getting there network but Airtel India is least bothered to look into this matter. I have paid 6 months advance rental including tax against which Airtel India provided me the Wifi hotspot Power backup Datamax 01 datacard. Now I am feeling cheated because Airtel India is not providing the promised service.
