<prompt> Human: Hi,I got a call from a small attorneys office called Crystal Moroney about an alleged debt for not returning a book. I asked them if they could send me itemized billing, but they said it was not possible. On the first call, they were pretty polite and asked me if I remembered a debt for a book return. I told them I dont remember anything like that, and they told me theyd give me a bit of time to do research before calling back. I asked if they could send me verification like to whom the debt was owed, but they also seemed to deny being able to do that. I am a college student and have rented a book, so it is possible I may not have returned it, which is why I havent blocked them. They called for the second time this morning and asked me if I was ready. I asked them what the payment options were, and they said online, money order, and over the phone. I needed to leave for class, so I just said Id try to get it paid by the end of the month to get him off the phone. He said hed put me down for April 29th. Did I make a mistake and admit debt or something to a scammer?He was asking for somewhere around 250. If it is an actual debt, Im thinking of just waiting for it to fall of my report since I dont see myself needing a new car, house, or new card in the next 6-7 years.Thanks for any insight!Additional info:  <response>: Googling the name of that firm brings up a lot of complaints about apparently shady debt collection. Definitely conduct all of your interaction in writing, and insist on proper validation of the debt - as theyre required to provide on request - before paying them anything.
