Airtel — SIM card services stopped without any reason

My sim card is not working from last 5 days.. I registered complaint 1000 times and i was suggested to take a new sim from the store and was assured that services will resume in 24 hours... It has been more than 48 hours also still it is not activated... I registered 1000 complaints calls but they didn't respond and resolve my problem.. As my all bank accounts are linked with the number i am not able to send or access my accounts at all. these 5 days caused a 3 lakh loss to me and my organization as the clients were calling me continuously but unfortunately, they were not able to communicate.
