This company contacted me in XXXX @ XXXX. The gentleman that contacted me identified himself as XXXX XXXX. He said this was a business matter and began harassing me to tell him my personal information. He told me that he needed my date of birth and my address. I said to him that I had no idea who he was or why he was calling and I was NOT going to give him my personal information because I did n't know who he was or why he was calling. 

He never XXXX time identified himself as a collection agency, he refused to tell me what company he was working with, he just kept pushing me to give him my personal information. And told me he would n't tell me who he was and why he was calling unless I gave him my personal information. 

I called the company back to speak with a supervisor, and the operator hung up on me each time I called back, XXXX times in a row. The XXXX time I called back the transferred me back to XXXX XXXX who again only wanted to take my personal information.
