Sunil Bharti Mittal, founder and chairman of Bharti Airtel, on Thursday said that adjusted gross revenue (AGR) issue is an unprecedented crisis for the telecom industry. Mr Mittal's comments came after he met telecom minister Ravi Shankar Prasad to give an overall view of the industry. "Committed to complying with the Supreme Court order on adjusted gross revenue (AGR), and Bharti Airtel will make the balance payment expeditiously," Mr Mittal told reporters.
