I had booked a flight with an airline through my chase credit card. It was a connecting flight and the airline canceled one of the connecting flights but didn't cancel and refund my trip. So I tried to cancel my entire trip but airline didn't allow me to do so without a heavy penalty. So I filed a dispute on credit card and I was credited back the amount. Three weeks later, airline issued a partial refund and I now have both the credit as well as refund on my card. What should be my next step? Wait for chase to take back the credit? Or contact them through email or phone?
EDIT: The refund amount is a little lesser than original transaction amount since the transaction was in foreign currency and due to the fluctuating currency rate, I got a lesser amount refunded. Do I have an option to get the difference amount back too?
