Airtel — no proper service by front end employees

Address:

Daman, Daman and Diu, 396210

I've bought a new mobile and my airtel sim is not supporting in my new phone, where as it is working in other devices. And when i visited the nearby airtel office the employee over there was not able to solve the problem but without hearing any problem he was answering in very rude and unprofessional manner.
I'm very disappointed with the service of the person and if in next day my problem is not fully solved i'll switch to either jio or vodaphone.
I request you to train your front end employees how to talk and behave with the customers.
