Airtel — Poor internet service for a long

Airtel prepaid service provider is not solving poort internate connection from last one year. I am complaining from nov'21 till date. They have cheated me of double recharge of Rs 479 on same time on Dec'21. Assured me of providing uninterrupted internate connection from Nov'21 till date. Even his Nodal officer/Appelate is not picking phone now. They are closing my service request very often without resolving the problem.My mobile no is [protected], Orissa. I have no option than to switch to other network. All are saying wait from nov'21
