Airtel — mobile number portability (mnp)

Address: Lucknow, Uttar Pradesh

After my request to port out from airtel to other service provider, I received a call from no [protected] from airtel on 13th Jan 2020 (06:18 PM IST). Person from other side naming himself "Tarun", talked very rudely and threatened to reject my request. In fact I have not received any message till now from airtel regarding my MNP even on 18th Jan 2020.
Kindly arrange for my MNP ASAP and please make sure rude and frustrated persons like "Tarun" are never given the task of strengthening the consumer-service provider delicate bonding.
Thank you.
