There are several complaints against them on the internet. They call but never leave a message. I answered a few times and it was a recorded message telling me an agent would be with me shortly, well if you are going to call there better be a live person on the other end. I called back and asked what this is concerning and was treated very rudely. I asked for written documenation on this so called debt and they told me to pay up. I just hung up, I refuse to be treated like that and I will not give just anyone any information over the phone if you can't provide me with proof. I am filing a complaint with the FCC and Attorny Generals office.
