Whirlpool India — Whirlpool Service man AMC delay fraud

So I Bought a whirlpool fridge and before the buy date called several times to extend the warranty through amc and the next day of completing 1 year product buying date . The whirlpool serviceman came and talked how he can make it so that we bought the amc before the purchase date and took some extra money even though I started calling them 1 month prior but they did not pick up and even when they did they did not came . What kind of behaviour is this to get some extra money service man did not attend our calls just imagining how many more people they took money make me fell uncomfortable.I would like my 200 rs back cause I should not have had to pay them money.
