Account status. To whom it may concern : My name is XXXX XXXX and in 2013 I had issues with an apartment building I was living in and it left me with debt on my credit report. I recently paid off the debt and it was removed from my credit report. XXXX XXXX was the original creditors and they sold my debt to XXXX different collection agencies.
