<prompt> Human: Hello.I moved out of my previous house last spring without realizing I was still the account holder of the internet at the place. I recently received a letter from credit management saying I have an unpaid bill of 143 that was sent to collections. I guess my ex decided to keep using the internet and leave me with the bill. I checked with the ISP and my unpaid bill with them is about 15 dollars less than what credit management is asking for. Why is that and who do I make the payment to? ISP or credit management? And is there anyway out of this or am I stuck paying this?Thanks in advance!  <response>: You mean you didnt cancel your internet and forgot to pay the bill. Whether anyone was using it is immaterial. As to who to pay, use the links below to figure out whether to pay the original bill or the bill from collections.
