MTNL
Wrongly Charged For STD Calls when Not Made by mtnl

I've been using the mtnl service from a lonf period and my number is 26045285,

the problem is that i've been charged for the std calls that i've not made and i was also not aware that std calls can be made through my phone and after getting the bill and the call list, i tried several time to call few known std numbers but failed to do so becuase it can't make std calls and more over this phone is used just for broadband connection, after i've sent the mails to concerned people i got a call from them that sir u've made the calls and u've to pay the bill and i tried to tell him that how can std calls can be made when i'm not able to make these calls from my phone then he asked me to call a lady at the switch room, and she also said that std service is present since 2001 and i told her the same thing abpout i am not able to make std calls from my phone but she didn't listened and therefore then i asked her to please disable that service for the time being,

Please help in resolving the problem asap.

Regards

Arpit
