XXXX Capital Management contacted me on XXXX. They threatened legal action ( XXXX XXXX ) and when I offered a settlement, once they send verification of debt, they told me I was insane. I asked them to stop communication with me, and that I would deal with XXXX, the supposed creditor. On XXXX XXXX, I received a letter from XXXX again demanding payment, this time stating that I had made payment arrangements with them, which i did not. When I called to tell them I had done no such thing, and neither they nor XXXX had provided debt verification, the person stated that he would end the conversation, and ended the call.
