Indian Railway — Issue tickets for route diverted trains

Address:

East Singhbhum, Jharkhand

Sir,
Due to Maoist attack threat Indian railway diverted the route o[censored]tkal kalinga express (8477,8478). Train is now skeeping KGP, TATA and no of other stations but still they show availability on websites as well as tickets are being issue at reservation counters. I took the ticket from Bangalore counter and when after knowing from my friend about the diversion fact i went to cancel the ticket, i had to pay cancellation charges consequently which is just a kind of fraudulence.
If train is not running from that station how come they issue the ticket to the passenger, if given why are the deducting cancellation charges? they have not updated their database for this change and this is not a 2-10 days change its being in effect from last few months. trains are not being departured from TATA to KGP and vice versa in night after 8PM.
