This number calls several times a week but I always miss the call. I was finally able to answer it today. Guy said he was from Glass Grove or Grass Grove Capital, that the call is being recorded, and that he was calling regarding a personal business matter. I asked him to repeat where he was calling from and he just kept repeating that it was a personal business matter and attempted to verify my mailing address. He was VERY rude. He then said "I know your social security number. How would you like it if I just gave that information out to someone without verifying who I'm talking to?" I told him to mail me whatever he's needing to verify and hung up. I don't have any creditors that would be trying to collect some I'm assuming this is some sort of scam. BEWARE!!
