My cousin just went through some BS with them. They contacted her saying they're going to garnish her wages talking about she owed 17K. Accused her of not filing taxes since 2013!
When she absolutely did every year. She sent them her W2's , meanwhile they actually started garnishing her wages. Come to find out that they were wrong and she was paying Philadelphia taxes because she worked in Philly and now they have to return what they took from her and are taking their good 'ol time doing it. She said they're ignorant AF too.
