Airtel — portability issue [protected]

I would like to register a complain regarding my number-[protected]. As i am using airtel postpaid in delhi circle and requested for airtel pre on post in j and k circle in october 2019. Its been more than 2 month but my request is still pending. Even during this entire period, i went multiple time to bahuplaza airtel outlet but they refuse to help me as they claim everything is okk from there end. I also tried to register complain through customer care even they fail to help me out. Now i would like to request you to help me as soon as possible, it is already more than 2 month and there is no sign of help from your side. Please resolve my query.
