My son XXXX XXXX XXXX XX/XX/XXXX was hospitalized a few months ago and my ex husband XXXX XXXX XXXX signed as the guarantor with his ss # for XXXX. Optimum Outcomes Inc has called me and harassed me for the debt when I explained they have my name and his address. In no way did I sign any papers taking responsibility. XXXX took him to the hospital and signed. I only was on the chart as emergency contact from his XXXX.
