Its totally dead for more then 5 months.
No complains are entertained, no response nothing.
Need to cancel it. Since no proper channel to maintain.
No office in nearby are where we can give letter or can visit personally to solve the complain. Whenever give call to customer care, they give complain number and says in 24hrs your matter will resolve, after that i called up couples of time without solving complain they again give me new complain number.
