I have received Airtel landline bill which has unidentified STD calls to some number in West Bengal mobile (about 100 calls). I did not make any of these calls. These calls were made during day time Mon-Fri, when me and my wife both are in office.
When I called Airtel, the customer care say that "Airtel is such a big company. They would not do such a small thing." Despite of complaints they did not revert back to me.
I think their line-man or somebody else has tapped our phone and used.
I have since then locked my phone and also switched to BSNL and would disconnect Airtel landline.
My question is what if some unsocial element had done these calls? Is there any way I can complain to somebody about these calls?
