BSNL — Bill due even after disconnection

Address: Punjab

Dear Sir/ Madam,

This is to bring in your kind notice that i had disconnected my wimax connection number[protected] months back . i have given my application at Rialto chowk office. i also cofirmed about disconnection of my wimax connection but yesterday i received email that my bill is due and bill amount is Rs.258. Kindly check it otherwise i have to move to consumer court for such mistake.
i hope for a favorable response.

Thanks and Regards
