Hunter Warfield is a collection agency based in Tampa, Florida. They are an 2 on the 10 point scale of debt collector shadiness – they have an actual website and don’t try to hide their business address.
The only time I have encountered them they were collecting on an old apartment lease. Their business location is:
4620 Woodland Corporate Blvd
Tampa, FL 33614
I have represented clients against Hunter Warfield before, though I cannot divulge the details due to client confidentiality concerns. They are not a scam outfit and they seem to make a decent effort at verifying their account info.
