Indian Railway Catering & Tourism Corporation [IRCTC] — less amount received as refund

I got reserved (To my wife) a e-ticket to 17229 sabari express from guntur to secunderabad on[protected] for rs.190/-. My pnr number is [protected]. But, the train was cancelled by railway authorities due to floods in kerala. They have also cancelled my ticket and gave me refund of rs.70/- (Less amount) by deducting cancellation charges of rs.120/-, which is against railway cancellation terms & conditions. As per the railway policy the full amount has to be refunded to the passenger, if the train is cancelled. Where i got 120 rs. Less refund (Deducted as cancellation charges) into my bank account. Hence, i request you to direct the railway authorities to give credit of balance amount of rs.120/- to my bank account immediately. I have sent a e-mail to [protected]@irctc.co.in and [protected]@irctc.co.in requesting the same.
