Consumer Redressal

Hi,I am a Delhi Vodafone postpaid user with number 8860137270.I talked to the vodafone customer care on 11th or 12th may regarding what will becharge for using the postpaid sim of delhi in Mumbai and also the the free call snd sms gives to me for the minimum charge I pay. He said that till I use my free calls and sms I would only be charged my minimum bill of 99+service tax,but now my bill has come and it is very high,every call and sms has been charged.Why? why wrong information was given by the customer care,I asked them to check the recorded call they would have kept with my number made to customer care.I want this to be corrected and why I should pay for the wrong information given by the customer care. I asked him like many times whether I will be charged or not for free calls and sms and he said \'NO\'.I asked them to correct it but they are only regretting for the wrong misrepresented information and asking me to pay.I was given the wrong info to just earn few bucks more
