Debt colection company hoping that I will call them back for an unsubstantiated debt, there is none. That is why I won't call back. I just cleaned up my bills, and had a law firm do all the work. This company believes that they can make me call them, I will not, I will change my phone number fist, they can kiss my shorts before I will interact with them. I own no one past due, my credit score is excellent, my bills are all on time. Don't even call them back, I never speak to unknown people on the phone, unless I research them first, these people are scammers . . .
