This is some scum bag collection agency. I called them back, and they claimed the didn't call me and had nothing listed for my phone number. Liars!

I asked them to take me off their calling list. She claims they don't have one, and said they only call those whom have accounts with them. I have never heard of them, and I don't have any debt to collect.

This is a debt collection agency. Very rude.

I don't have any business with them, yet they call my house and are nasty to me.

Client Services is the company, and they are calling from Denver Colorado

Shows up as "unknown caller" on my caller ID.  I picked up, and was told by a computer to "please continue to hold".  I hung up.  If they are indeed a "collection agency", they are barking up the wrong tree.  I have a stellar credit rating with NO adverse entries.  I have NEVER had anything go to collections.  Obviously these are bottom feeders, who will try to intimidate if you let them.  I won't be picking up again.

These [***] heads keep calling me, and when I call back they claim they don't my number
