not good as in the name of skoda

i m the owner of the fabia white car , i had a bad experiance about this car,my car gives avg of 16km/lit as compare to company claims 22km/lit, this car has no extra ordinary quality as like of price, even the krishna honda sales who is the authorised dealer in chd, not treated well with the customer,they r not even bother about the customer, i have so many problems in skoda fabia, if a company got my message and contact me 09815283248, i m in very much trouble after purchasing a fabia.bad fuel economy,bad staff behaviour.
