Off Amazon, relo payback, f-ing useless HR

Amazon is terrible even after leaving. After leaving and trying to contact HR about the balance of relocation payback, days later I've received automated email asking me if I give permission to have the amount subtracted from my final paycheck. I replied to that email asking what is my final paycheck amount. No response. I called the number listed in that email, and it said someone will call me back within 24 hrs. No response. I called and emailed HR partner several times (I had her contact saved cuz I knew this would happen) No response. Seriously fuck this person. I just gave permission to subtract relo amount from my final paycheck, and got a automated message saying it will, and they will contact me if I have to pay more. Oh and the deadline to pay all back is 3/30. Still haven't been contacted. So basically I have no idea how much more I owe, nor what my final paycheck was. Anyone who left this fucking place that can tell me what I can expect? Thanks.
