Amazon India — amazon is fraud they took my money of cancelled order

Amazon is behaving totally fraud they have charged me for cancelled order

I've order a mobile on 30th december and immediately cancelled after bcoz of wrong model but the product was not shipped at that time.
Since 1 month they are cheating me every time i call they are giving 72 hrs time and refused to send mail on this. Almost 100 times i call to amazon sometimes they told the regular executive statement have no value only senior team will tell you the truth means amazon have a cheater team

I never expected such a wrost service from amazon it's like hell
