VLCC Healthcare Ltd. — regarding discrepancy in rates of hair rebonding

I went to vlcc, jhansi for mid length hair rebonding they charged me 6000 rs for it and told me that this is under an offer .and if I don't book an appointment with them at the earliest their so called offer will end and then the price of rebonding will increase by 20 % .although I was not interested but they called me again and again and convinced me that i m charged much less and i am getting a very good opportunity which i should not miss.believing it i paid them the whole amount.the very next day my neighbor went to vlcc just to ask about the rates of her length hair rebonding.her hair length was more than double of mine and after couple of calls from vlcc jhansi, they were able of convince her that she is also getting concession as this is again an offer.they finally came down and charged 5000 for it focussing again and again that it is under an offer which she should not miss.it should be noted that actual cost of long hair rebonding is 10000 which they had shown me in their rate list..Am I supposed to ask vlcc that is vlcc a famous branded cosmetic care in India where customers can go and rely on it blindly as i thought earlier or a vegetable market where customers should think twice before going because their workers are bargaining and ruining the aura of vlcc..
