Do not confirm your name phone number or e-mail with these people. I cancelled my Comcast service in person and they confirmed that I never leased their equipment during the cancellation process. Two days after cancelling comcast I received a phone call from Nicola with the "equipment retrieval department". She claimed I had a telephone modem. I didn't have telephone service, nor did ever have any comcast equipment. I'm a bit concerned that my name, e-mail address and telephone number were so easily accessible by whomever these people are.
It's a recovery company. They work for Comcast and other cable and satellite companies. They're subcontracted by these companies to recover their cable boxes and satellite equipment that hasn't been turned in by previous customers.
