Meru Cabs — complain

Address:

South Delhi, Delhi

hi,
my name is balwant bisht, i had booked meru cab on 22nd sep 2010, from lajpat nagar to old delhi railway station, the kms was 11.7 and they charged me Rs235 which was very wrong, i have all the receipts with me.
they should have charged me 219.35(11.7X18.75), as i traveled in night. i dont know what to do??? they must have charged me in past as well.
