<prompt> Human: An agent from Heritage Portfolio called to warn me of a debt owed to Sprint from 2011. They have my date of birth, social security number, address, and phone number. They also said if I dont resolve within this phone call, theyre required to forward it to legal with the notation I refuse to pay, in which case, it will be sent to a judgment and be subject to treble damages and further fines. Ive never had a Sprint account ever. They wouldnt give me even an hour to make some phone calls to figure out my options. I ended up getting it divvied into thirds and paid 124.24 while protesting the payment because the call was recorded. They wouldnt let me pay with a credit card, allowing only a debit card. I dont know what to do at this point. --Update: Thanks all. Killed the credit card. Im going to Sprint on Monday to see if I can find anything specific on the charges.  <response>: Youve been scammed! Never pay or give information to someone who calls you.You need to contact your bank and cancel your cards immediately!
