Jetairways — Over Deduction of Ticket Fare

I have purchased a ticket for Doha-Kochi-Doha (PNR: GPUNXV) using Credit Card of my friend and the fare was shown QR 2571.00 in the Website and in the Ticket but QR 2799.70 has been debited from the Credit Card Account. Jet Airways confirmed that I opted Qatar Riyal for the payment and the Credit Card currency also in Qatar Riyal. Please be requested to note that the issued e-ticket in that the transaction currency in US Dollar while I opted Qatar Riyal as currency. So it is clear evidence that the mistake happened from Jet Airways and further Jet Airways requested to refund my extra deducted money ie. QR 228.70
