Wakefield and Associates Mistake on my Credit Report Aurora, Colorado

Dear Sir or Madame;

      I have learned that Wakefield and Associates has posted a bill from Carepoint P.C., account # 150787880, for $246.00, whcih was paid woth check # 134 i Feb., 2012. They aslo failed to inform me that another bill for exactly the same amount was submitted. This bill contained a complaint about a doctor in the ER. Consequently I thought this matter was closed. There should be no negative charges on my credit account. Pleasse help cleart this up. Sincerely, Brian Lasater
