The amount will debited from my account but store cashier said that he didn't receive the payment.he said the amount will credited in your account within 24 hours.after that he said all the bank details and he said the amount will back to you within 7 days . After 7 days he said you have to wait 7 days more. After 15 days I didnt receive my amount... still
