Maurader Corporation on EXP report. States that I owe 1307 (really on 755 w/o interest). I disputed with the CRA and it came back verified. I then sent out two validation letters finally getting a reply from the second one stating the 755 due, not the 1307 listed on CR. I then sent a settlement letter asking them to sign it if they agreed to the settlement or if they didn't agree to make me an offer and send it in writing to me. I have not heard from this company since sending this letter on 8/11 CRR (they rcvd. it on 8/16. What should be my next move?
