[Resolved]  BSNL — Received Bill after 13 month of closing internet connection

Address:

Haridwar, Uttarakhand

Sir/Madam
This is very shame full to inform you that some days before i got a bill(near about 7000 Rs)
for our i,nternet connection which be have closed in May/June 2009.
After closing our internet connection we received no bill, but surprisingly in june 2010 we received a bill claiming previous due of near about 7000 Rs.
Sir, for that connection i have even received security money for that connection(via cheque from bsnl) and
that cheque has been credited in my account on 22 oct 2009 with Transfer No-392400.

For which connection i have received my security money back how can i get bill for that connection??????

hoping for an action very soon
