This is with regards to a notice from " Merchants & Professional Credit Bureau Inc '' A/C No : XXXXThis company has been trying to collect a debt that i do not really owe as i have worked with the debt owner ( Medical company ) on why it was paid by my insurance. 
This collection agency has not paid heed to all my communication in this regard and went ahead with reporting this to all credit agencies. This caused my credit score to go down drastically and prevented me from getting a mortgage on my new home.
