Airtel — services not received since 2nd march

This is arnab. I have the airtel number since last 5 years. On 2/3/18, suddenly i started receiving random calls. I suspected that my number must have been given to someone else. I called up the customer servuce and they confirmed the same. They said they would give me a call which i have never received. However, the issue was resolved by next day for few hours. After that my service got deactivated and there was no network. Called the customer service again and they said they would resolve the issue. However, no calls and issue was also not resolved. Again, i called up on 17/3 and shriram picked up the call. He put me on long holds and then when he could not do anything he passed on the call to biplav. Biplav promised that the issue would be resolved by 4 pm and he would call up by 5 p. M which he never did. Atrocious service with dumb people in customer service who do not have the basic courtesy. Till now no calls, no apologies, no service... And this is my primary number
