Respected sir,
I am highly disappointed with the idea postpaid services . I was charged meaninglessly 1300 inr for a month . I refused to pay the bill and asked for details, but none of the customer service agents helped me out. Infact my number was disconnected, due to which i faced i lot of problems .They crossed the limit when i got a bill of 19000 inr and that too just for 20 days .I asked for details and again i got no response . I want you to answer me that if my credit limit for an idea phone number is 2000 then how could you charge me more than that ? Without any reason ?
I am so disappointed with idea, i want to file a case against this company .
