I spoke with an agent and I asked if I could get documentation to verify I owe a debt and he says no I would have to talk to my insurance since they made an initial payment. I told him the letter they sent said that I could dispute the debt and he says " you do n't know what dispute means '' I said he was being rude and unprofessional and I requested to speak to another agent or supervisor and he says " they do n't have time to talk to people like you ''. I said are you refusing to let me speak to a supervisor he says " yes, I am not going to bother them with your issues '' The agent refused to provide me with any information other than an amount owed and the name of medical facility, refused to allow me to speak to a supervisor, and talk to me in a demeaning way throughout the conversation.
