Monte Carlo — Fraud bill given to customer

Address:

121003

I bought a Jacket on 40% offer was going, its total original price was Rs.3495/ (Inclusive all taxes) so, after 40% deduction its new cost was Rs.2097/ but I see in bill where again VAT of Rs.104.85/ and Sur charges of Rs.5.24/ added in the bill cost and became Rs.2097+Rs.104.85+Rs.5.24=Rs.2297/
My concern is if all the taxes was included in the original cost then why again all taxes added after deduction.
The same are being dome with other customers so, how a Showroom retailed making fraud and cheating to customers.

Harish
