Wirlpool is not giving back our money for a faulty fridge

Location/place: Bangalore

Name of company/service: Wirlpool

Hi

I have purchased a Fridge from Wirlpool. After few days I found it is faulty the Door is not properly fit in to the fridge.I called the customer care and they said they will replace it. After that for last three months they are just playing game, instead of replacing fridge or giving back our money. I tried lot of times to talk to whirlpool, either their manager switch off the phone or the customer call center people do the same.

So I am quite helpless to get my money back.
