Xfinity modem update scam phone call

Just got a call from a local number. It started off sounding odd but possibly legit and then started sounding a lot like a scam phone call. The guy claimed he was calling from xfinity and wanted to know how my modem was working. Said that the updates that were sent to it didn't work and asked me about the lights and what was blinking on my modem. He also asked if i was having problems with my internet service (I'm not). He wanted me to connect my computer to their website. I hung up. The guy sounded like he was in a big call center and he had a non- native English speaker accent (sounded like he was from India or Pakistan).
