from No of months i am recieveing the extra bill for calls even i do not use my landline no for calling usually. I found the no and made call on these no they were around my office area. Accentual these were made by the airtel operators during the phone line tasting.It is happening from a long time but i have paid attention in last few bills.
In this month again the caller tune charges are added and customer support says it is again activated by you even in this month i have locked my phone and operated by me only.
this is not good act done by the tele companies who are making the wrong bill for those costumers who do not pay much attention on the bills and which is not rationally possibly regularly.
I am sending a bill copy of this month .if needed then i can send all the bill copies immediate.
