Calling daily. Calls are made by a robot. This is evident because there is no one on the line when I answer the phone. When I do answer, the person talking to me refuses to disclose that they are a collections agency. I spoke this morning with " XXXX '' and to " XXXX, '' both of whom refused to tell me what the call was referring to and required my phone number after which they would transfer me to another representative. I refused to give my information to them. XXXX hung up on me. She refused to give me the company name and address. She refused to allow me to speak with a supervisor. XXXX gave me an address then agreed to transfer me to a representative but instead I was disconnected.
