Airtel — airtel sim network

My airtel number [protected] is 10-12 years old, when its network really best in performance. But from last 2 years its network is became worst. I complained so many times, every time i got answer from airtel cc team that network-connection/tower is under maintenance, and its till the time not fixed. The cc team have only default lines in answers as they were trained like that to make fool customer/public. Now a days, airtel sim is not able to connect any call or sms for bank otp or any message. Its recharge is also very costly on monthly basis. A middle class person bound to gave them money as in recharge whether sim network functioned or not. I faced this issue from last 2 yrs. And through out at delhi n other states. There is no a solution to airtel cc team/nodel officer - khan / management. Its my primary number and registered with banks / other websites for business. Nobody helping me out from this issue. Cc-121 not able to gave any solution, they don't know anything. Its really irritating.
