[Resolved]  Idea Cellular — Converted from idea postpaid to prepaid (still fraud new bill received)

I have called before to customer care but they either ignored my issue and blamed me for not paying.This time i written on social media.Idea customer care themselves called me and discussed on the issue where i explained them all the scenario again but this time they accepted the inconvenience caused to me and the issue i addressed to them about their system.It was there system issue where they where not able to calculate the final amount while converting postpaid to prepaid and the bill raised as it was calculated on different call and data rate.I explained them how the bill amount would have been reduced if there system would be proper.I got ready to pay half amount as i understood some service i have used and not paid .So the idea cellular got ready to give me waiver of 150 rs but as it was already converted to prepaid they topup a talktime of 150rs. and i paid the final bill amount.
