Consumer Redressal

This Complaint is regarding the customer care dept of Airtel. I have been using their landline and broadband connection for quite a few years now. I was using the landline connection only because of a plan they had made available to me. They deactivated the plan without my knowledge, i continued using the landline and after a month when i came to know about the changes in the tariff i gave a complaint. I have been calling them since dec 2012 now. I never get an answer back and they keep saying i would get a call back by the end of the day which doesn\'t happen. I gave a request for the reactivation of the old plan, they haven\'t given me any feedback. I don\'t know what is the present status and if i can use my landline with the same tariff.
