I venkatesh p swiped my mastercard debit card belonging to canada bank savings account at mathaji electricals belonging to idfc first bank on 25/03/2019, a sum of ₹15, 750. The amount has been deducted from my account but it is not been credited to the merchant bank. When i enquired regarding this in the canada bank, they gave me a letter after 5 months (04/09/2019) telling that the amount has been credited to the merchant bank on the same day of swiping the card. Hence i have also raised a complaint regarding this issue to the national consumer helpline with the complaint number 1582645. Please check to the issue and refund my amount as soon as possible.
