What can they do?

my sister and her husband do all they can, but they barely get by. Their daughter has a congenital bone disease and it requires my sister to be home providing around the clock care. Her husband works sixty hours a week, but they barely get their bills paid. They are going through a rent to own place to purchase my niece's bed because they couldn't afford one outright and they pay every 2 weeks. They were late with their payment last time but did get the payment in on Tuesday. On Friday, the repo guy showed up because of a misunderstanding, but he called the office from their home and realized he wasn't supposed to take the bed. He then told them their next payment was due Monday and asked for a check to hold for the next payment. They don't have a checking account, but told him they'd be in Monday with cash. He lectured them about their payments and left. Later on, my sister had to run to the store to get some depends for my niece and he was in there- off the clock- and (continued)

in front of other customers started interrogating her about her finances saying "If you have the money to come here and get stuff why didn't you have the money to give me for next week's payment?" and stuff like that.

He humiliated her in public. All she had was about twenty dollars and she needed to get the depends for her child. I'm infuriated that he treated her this way- they do their best- they're hardly ever late paying any bills, but last time, they were and they paid the late fee. They are just trying to take care of their daughter- and he was way out of line.

Report the incident to his boss. He was unprofessional and I am sure his boss would like to know. He will deal with it.

Mnwomen is right. There is no legal remedy here other than a complaint to his boss.
