New GE profile refrigerator bottom

Question

new GE profile refrigerator bottom freezer model pfss6pkwass. Will not run, stuck in display mode. Lights are on but when setting temp on panel it goes back to off after a few seconds. After spending 2000.00 at best buy they cannot send a tech out for three days to unlock the display mode. (of course they took my old fridge that was working fine) Any help would be great.
