I was called early morning by this company call COL Mediator, said I owe money to this other company. I ask what is their phone, they say, 855-546-9131. I call back they don't answerer the phone. I look up this phone number; its a no posts type phone. So, always ask for their number first. It's a scam..I thank you "WHO IS CALLING FROM" for checking on this issue.
