Liars. Called and told me they sent out two notices to my address that got sent back to them for blood work a year prior I never got done. They wouldn't provide me more information without me providing my social security, nice try, I reported them and will be pursing this. Very unprofessional lady I spoke with who argued with me about how they aren't a "scam agency," but wouldn't give me information. If they aren't sure who I am when they call me then they have no business calling me. Furthermore, I think I would of gotten a bill from wherever I supposedly got blood work done before getting supposed notices from this collection agency.
