Just accidentally took a call from this number. They are a collection company out of Tennessee. The lady who called was rather short with me and a bit rude when I refused to give her my name, address or social security number over the phone. I then asked for her name. She said she was not allowed to give me her name, but she did say the name of their company is "Assisted Collections, LLC" and they are a collections/wage garnishment consulting firm (whatever that means).
Anyway, I couldn't tell if she was legit or a scam, so I just hung up on her. I wasn't able to find anything online when searching Google for "Assisted Collections, LLC" or 423-375-0345 (the phone number she called me from), so I'm placing a warning here for other people who she might also be calling.
