<prompt> Human: A collection agency contacted me about a debt from 2014, for 500ish dollars. I sent a verification letter and learned that I apparently had a 350 ambulance ride. The credit agency has my information correct- old address, social security number, everything. The only problem is that I have never ridden in an ambulance. How do I continue to dispute this debt? They reported it and it is a negative mark on my credit report! Any help is appreciated. Thanks!  <response>: Contact the ambulance company directly and have them provide you with the record of your supposed ambulance ride.
