Airtel — fluctuating network

Its been more than two months, my airtel number [protected] has a continuously fluctuating network.
For data network fluctuates from 2g 3g and 4g - and sometimes internet is not there.
For calls - call drops any time in middle of calls.
In my family all are using airtel apost prepaid and all are having same issue be it post paid number or prepaid. Its high time... Now...
Your open network coverage show excellent in my area but network is pathetic for last 2 months. My using airtel since 2004 but seems time to give up.
