Okay, so I got sent to collections from Rio Resources, and got sent to Accounts Recievable Management of Florida. I sent a debt validation letter and a cease and desist letter, Certified Mail with Return Receipt Requested. I know that they recieved the letter, as I tracked it, but I haven't gotten the green card back. I haven't heard anything from them, and I sent the debt validation letter back before the 4 of the July, like I think the last week in June. So, what happens now? Do they report me to the credit bureaus? Anyone had any experience with this?
