Bharat Sanchar Nigam [BSNL] — Disconnection needed

Dear Sir/Madam
My Bsnl connection no[protected] landline and broadband both are faulty since months.After series of complaints nothing has been done and every month huge bills are billed. In such case its my earnest request to disconnet the line totally. I do not want to have any more service from Bsnl.
It ll be helpful if you do the disconnection asap

Regards
Madhavi
