Payment rejection for a booking

<p>This morning I booked an air ticket and paid. I received an email and sms confirming the booking. A short while later I received an email stating the card I used for payment had been rejected. I immediately called and was told I couldn't pay (with the same card) because that seat is gone already!!! SAA has listed the card for some reason- hence the payment was rejected. However, this is not a hot card or anything **********. Kindly reinstate my booking, at the original price.</p>
