Product: Debt collection

I was contacted by EOS USA at XXXX XXXX  EDT for an alleged XXXX account Bill. On the first call, I did not catch the females name. She attempted to verify right party contact, but provided me with the verification information instead releasing XXXX XXXX XXXX. I asked where she was calling from and what her company business was. She said she couldnt continue call but told me calling from Texas for a personal and private business matter. I asked for a supervisor or Manager, but She eventually hung up on me. I called the same number back XXXX as it was a New Jersey area code. I spoke with XXXX, he would not give me any further details on his position at that company such as extension or representative id #. I thought that was odd as XXXX is a common name. I Asked if all calls were recorded, he said yes. Asked where his company was from -Texas XXXX He attempted to verify right party contact. He, similar to the prior representative again gave me XXXX XXXX XXXX, I said XXXX NJ, didnt know zip code, as prior address. He advised me there that this was a communication from a debt collector, but failed to tell me any information he obtained would be used for that purpose. Without telling me what the debt was for, or how much I owed, he proceeded to threaten me with collection efforts, saying its a fact there will be collection efforts trying to persuade me on paying a bill I have in the past disputed. I proceeded to ask what those efforts were and asked if I would be arrested? He responded it is up to XXXX. I advised him he was threatening me and he denied it and eventually hung up on me after once again asking for a supervisor or manager. He said he cant get in contact with them and to try later and gave me contact # XXXX. I reiterated, they originally contacted me, I would like to speak to a supervisor and wouldnt mind waiting. He hung up on me. I called the new contact number, same business for a 3rd time immediately asking for a supervisor or manager to rectify prior conversations. Spoke with XXXX and she said non available again. I told her I would verify information so we can continue call and see what this is about. She again did not go through right party procedure properly, realeasing both prior address XXXX XXXX XXXX, and this time releasing the last four digits social security number. I said yes to both address and ssn, as she gave both to me and anyone can say yes, and I wanted to know why are they calling me at XXXX XXXX  and not giving me information on why they were calling until finally XXXX gave me the entire mini XXXX. This made me wonder why this company gave out my last 4 ssn to someone who just said yea they lived at XXXX XXXX XXXX She did correct me and say can call until XXXX, I said she may be accurate on that. I explained in both calls with XXXX and XXXX that they ( and first representative ) did violate the FDCPA in being deceitful and abusive by threatening me. I proceeded to ask XXXX if this is something XXXX would like to hear about? She proceeded to hang up on me. 

In all three calls I asked for a supervisor. In all three calls, they released my information. XXXX harassed and threatened me. XXXX defended it.
