Airtel — fraud with customer

Address:

New Delhi, Delhi, 110025

Last 4 days, in my area all other airtel sim is working, except mine.
I have been constantly calling them about my issue but they doesn't seems to responsible for that. The airtel customer care is fraud. And when i tried to convert my 4g sim to jio they denied and forced me to use their airtel network. These indeed shows that the company is doing fraud to customer becuase they took the recharge amount for 90 days and not allowing to use internet for 4-5 days, i feel like that's an harassment to the customer in case i have been calling since last 4 days.
