YES!!!! I went to the hospital for losing a toe and I now have 11 negative activities against my account and that is all people look at when they see my report, it does effect me. I am completely unable to even GET a credit card let alone any type of a loan. I'm screwed and have been ever since this happened.
As long as you are paying on the bill, it will report your payment history, but if you let it go delinquent and a collection agency is collecting the money it will go against you.
