Airtel — my vodafone mobile no ported out fraudulently

Address:

New Delhi, Delhi, 110085

For the past two weeks I was constantly receiving calls from AIRTEL representatives regarding a porting request on my phone no [protected] . My service provider was VODAFONE . After constantly confusing to the aforementioned airtel calls, I received a call from a person intimating as a Vodafone employee and he offered to clear the mix up and cancel any request made to AIRTEL. He said that a new request need to be generated and I need to provide him with the porting request number. The call came from [protected]. This incident happened on Jan 6 2018 . On the 11th Jan I found that my number had been ported out to AIRTEL under the name of some one called Paramjeet Rati.
Please take strong action regarding this matter as the number may further be used in various cyber crime.
