Airtel Postpaid — technical problem

Dear sir,
i am a airtel postpaid user from last three years, last year i take a addon connection on my basic mobile nimber [protected] my addon number is [protected]. From last year i am countinously complaining to airtel that i have a serious problem with my addon connection that(there is call from U.P east airtel suscribers that we have made a miss call to them , that's why they are calling) after facing this problem countinously i made a complain to my opprator (Airtel customer care ) but there was not a proper response from them they always tell that this can't happen you must have made a call . after many request to arring a call from technical department there is no response from customer care. i am facing a very hard problem from Airtel , please suggest me how to get rid from this irritating problem


Thanking you
