Airtel — fraud by airtel agent

I had port my vodafone no. [protected] to airtel on 22 jan 2020 by airtel agent rajeev kumar (Mob. No. [protected]) 9 days ago. From rudrapur uttarakhand.. I had paid total rs 500 but he still not recharged the plan. He had excused few days but now he is not picking up my call. Its a case of fraud. Need immediate action against airtel agent rajeev kumar. Hope you will take action against these frauds.
