Need some help with credit card collectors. Had terminated a line of unsecured credit with Chase Manhatten, 3 yrs ago. Been getting notices from Midland Credit Mng. Sent certified letters of request for validation and keep getting more letters with legal action. They sent me a copy of my balance with Chase that shows it was written off with credits applied by them ( Chase) giving me a 0.00 balance. Last lettter received asks me for documentation that proves my dispute. They have also placed this account with CRA as disputed. Any other options? Should I send this for arbitration with NAC?[b]
