Idea is terminating my connection and not adjusting the security deposit of 300 rs which i give in the beginning and also i have receipt of the agency who take money BEHALF OF IDEA . I have submitted 300 rs as a security deposit and idea executive tell me their is no deposit at all . How it is possible that u can give a postpaid connection without any security deposit . Now idea representative theft security deposit of customer?? From the beginning of this connection i have faced so many fake representative of idea.Next. Worst customer service of idea . How irresponsible idea executive is ? Neither they give resolution nor they have time to reply to my mail. Idea is cheating customer by taking security deposit and not return even not responding from a month.Worst customer service idea is.They just revert the pre formatted mail. Over 2 months no one responding with a resolution why? Where all senior executive gone ? No one in idea who track all those thing or they earn money by cheating customer . And send bill every month with add of late payment why ? Idea is not responding then why should i bear the cost of late payment . I wont pay a single unwanted late payment .
now i have to take action accordingly .
