Refused to provide me with letter of debt verification. After a lot of miscommunication (I was left with the impression a warrant for my arrest was to be issued if I did not pay them, I'm still unsure what's going on) I asked if they would pull a call recording and was told they would call me back, they never did. They were honestly soo volatile they gave me an anxiety attack. I'm still not sure where I have a debt to :(
