Taken advantage of during the holidays

@Walmart Supercenter I accompanied a family member who's special needs (MR) to the Walmart on Clinton Hwy in Knoxville during the holiday season. She wanted to get her money back on a layaway. She had $42 on the layaway and they gave her only $2 back. They told her it was policy afterwards (they didn't mention beforehand that she would only get $2 back if she canceled). She was understandably distraught, even crying. But what made us both feel outright disrespected was that the employees, after only giving her $2 back of her $42 layaway and making her cry, laughed like it was the funniest thing in the world. I haven't been able to get over what happened, to the point that I can't in good conscience shop at Walmart.
