On 24 march i purchased a prestige cook top from amazon using prepaid option and paid rs 2900 using online transition through atm card and the amount got debited from my account but due to some reason i canceled the order and rs 2900 was again credited in my account. But after some time the amount is reversed and sum of rs 2900 is again debited from my account and is not credited in my account uptill now.
Regarding this i had visited my bank sever time as the suggest i called amazon costumer care also number of time regarding this but they just move me like pendulam in between them
