BookMyShow — Online ticket of ki n ka

I have booked 2 tickets of ki n ka for date 10th april vide wincode no [protected] and[protected] for 250 each.L have been told that the amount payable will be 376.12.
This beingy 1st time it is a very bad experience to me that l have been told to pay so much amount extra on a ticket of 250 each.
Kindly let me know the details n deduct the extra charges levied if by some mistake on our or your side
