hi Sheila & Marcie.
Thank you for your kind input. Actually as of writing this post today, I have cleared all the ambulance debt. I paid directly to the collection agency, and I still have not establish credit history, by obtaining loans or credit cards or mortgage. Although, now that I have paid off the debt, and like sheila mentioned, I still wonder if any letter or 1 report has been sent to TU or Equifax, the debt in question was five months old with the ambulance and three weeks old with the collection agency.
I guess now, I have to find out if a report or any letter is already waiting till I try to get credit. Or maybe I should contact the two credit bureau to see what they currently have on file for me.
