<prompt> Human: My girlfriend is currently a student and has been paying on a medical bill on a payment plan for the past few months. There was 15 left on the bill and they sent over a new one for 75 and its about the 2nd time theyve done so and said even with payments on her statement theres nothing they can do for her unless she has previous bills which she doesnt have anymore. Is there anything she can do so they are required to adjust this? She only had the one bill so its not like it was applied to a different one.  <response>: ask for a statement and then go in to the hospital billing and contest it.
