I have disputed this in the past with this company to no avail because they do very little to investigate disputes. A medical office closed without sending me a bill and then put it into collections. I had no prior knowledge of the bill of only {$55.00}. As soon as I was contacted, I paid the bill in full. I am now trying to get a mortgage loan and being penalized due to this account. I do not have a single negative mark on my account other than this and I want it REMOVED. My mortgage company tells me it looks as though the negative collection has recently been put onto my credit report. Again this was a medical bill that is not even supposed to affect credit scores as of the new rules imposed.
