[Resolved]  Reebok Aviator — pricing high for the product

i recently bought a shoe from the reebok outlet nearest to my house.
i bought the AVIATOR (sheer grey /baby blue).the price of this shoe have been printed as Rs 1090 on the shoe. and same feeded on his computer . but the shop representative claimed that " nowadays this shoe is coming with the name PROTON and the price has been raised to Rs 1490,hence i will charge you Rs 1490 instead of Rs 1090 ". my complaint is that when i am taking the old version of the product hence i should be charged for the old version only ,why for the new revised version.
the reebok india company outlet from where i purshased the shoe is located at :
GD-23,MAIN ROAD PITAMPURA NEW DELHI
