Airtel — Duplicate sim not activated even after 4 days

Address:

Hyderabad, Telangana

I received the sim on 20.10.2021 around 12 noon and told that it will be activated by evening but to my surprise it has not been activated even after 4 days and there is no proper response from the Airtel office of Kondapur, hyderabad. Can any body helps in getting the sim activated. Phone no [protected] and the corresponding sim no[protected]u. My contact no [protected]
