I saw in a post from a year or so ago that these people are not legally able to sue-is that correct? How can you tell which collections agencies are legally able to file judgment? This company has called my grandparents about once per day. I tried calling their number back, but I don't get anyone. Yesterday, I received a letter dated March 15th. I'm sending a dispute, even though I'm technically 2 days over-because I got it yesterday!!! Anyway, I have no idea what the debt is supposedly for. It's about 2.5 times what I've ever owed for anything!
