Credit Card
Excess exchange rate charged on payment made via Credit Card

I had made the payment of 640 $ on around 22nd september'09 in the name of CFA exams. The exchange rate then was around

Rs. 47 for dollar, as per which the total fees amount comes to INR 30, 080/-

But the payment actually made was on 9th Oct'09 (as per Credit card due date). The exchange rate then was around

Rs. 46 for dollar, as per which the total fees amount comes to INR 29, 440/-

Now the statement that i received shows the payment made was INR 32, 566/-

So, you have charged me @ 50.88 per dollar (Dollar has never crossed this rate in last 120 days)

If you say of some trading margin or something, then that is also not beyond 20-25 paise.

Bank has charged around 2700/- excess to my account.

So, i request you to revert the excess charges at earliest.
