Is this real?

I recently called Xfinity customer service line to try to change my service. It instantly redirected me to a call center claiming to be a third-party device insurance protection center who immediately kept trying to sell me some yearly service and get me to give them a credit card number. One lady claimed they were an Affiliate of DIRECTV, another claimed that I must’ve just fat fingered the number and “it happens all the time.” I literally went to Xfinity’s website (the same one I go to to view my account info) and clicked on the phone number link from my phone, so I didn’t dial the number in. All three times I got sent to this call center. Is this a scam ?
