<prompt> Human: I went to a specialist early on this year around February on the recommendation of my doctor, and I went 2 times and it was basically pointless. Then several months later around mayJune I got called from the office and they told me they under billed me and I need to pay the remaining amount. I refused and told them it was their mistake to under bill me and I shouldnt be liable but they ended up selling it to some debt collectors. Now I just got a call from the debt collectors asking for the balance of 51.25 and I pretty much refuse to pay this out of principle. If I just block the debt collectors number what are the ramifications? Could my credit score be greatly effected by just a 50 debt? If I just wait out the statute of limitations on medical debt will the impact go away?  <response>: Could my credit score be greatly effected by just a 50 debt?If legit, yes. If I just wait out the statute of limitations on medical debt will the impact go away?Here you go
