If you bitch and moan enough and to the right people (ie. store manager) you could possibly get them to refund the gift card for cash. All POS systems will be set up to do that function. Most, if not all will need a manager security clearance to be able to access those POS functions. A more likely result would be a cheque mailed to you for the amount of the refund which would take approx. 2 to 4 weeks. Typically though, the refund of a purchase is done on the same media that was originally used. I can speak fairly confidently about this as it is the industry I work in.
