Consumer Transparency Group scam

I have been flooded with the recorded calls (womans voice only), I currently have a list of over multiple different phone numbers used by this company all from different states and cities. No one answers on the initial call, but sometimes if I call them back directly - I real person answers and when I ask who they are and represent - it is either Consumer Transparency Group or the "Consumer Law Group"?. I have asked them every time I can to please STOP calling me, I will never use their service. I have had them tell me they are connected to Experian and have some information of mine. I consider this harassment to the point of being threatening. At times, they are horribly rude!
