Sir,
It is humble request to you, kindly don't give people this vary much kind of service now a days.in the name of 4g we cant use your 2g service, my phone shows 4g network but, when anybody calls me it shows either switch off or not reachable (Phone has full network bars but when some one phone me the signal bars goes invisible).
My request to you is kindly solve your service related problem or discount our whole sims (In my family there are atleast 45 user of airtel but now all can think about to port in another service provider)
Thanks
Your user
