Xfinity telephone spoofing FRAUD ALERT!

I'm not sure where to report this, but yesterday, December 15, 2025, I received a call from an Xfinity phone number (1-800-266-2278) from a man who addressed me by name. He said he was calling to inform me that the security of my Xfinity modem had been compromised and it was being used by people all over the world. The man had a strong South Asian accent (from India maybe?). At first I believed him, especially since the call appeared to come from a legitimate Xfinity phone number. Then I became suspicious when he kept going into further detail, more detail than I thought a real Xfinity technician would go into. When I told him I wanted to call Xfinity myself regarding this issue, he immediately hung up. BEWARE.
