WE have a GE Spacesaver

Question

WE have a GE Spacesaver Microwave installed July 2005. I have tried to replace burned out nite lite bulb. Both bulbs broke from socket as I tried to unscrew. Bulb base will not unscrew. How do I get the bulb base out of the socket now that both bulbs are broken? GE will send out a technician at $75.00 plus parts, plus labor. They can't tell me how mush labor and parts will be. Sounds expensive when you give someone a blank check. I'm a retiree and can't afford their proposition.
