Where can I find someone to repair my musical Christmas decoration

I can't find repairman for musical 3 Santa stack decoration. It is not wind up, but battery operated. It stopped lighting up, and playing the 4 songs it played. On /Off switch goes back and forth and put new batteries in . Bought in TJ Max about 10 years ago, grand daughters favorite, and mine too.
