Google voice search results gave me the number to someone trying to scam me

So I used Google voice search while driving cross country moving out of state, I called to see about putting my service on hold since I was driving I used voice search and it was for Xfinity customer service number The number that popped up I called and a man answered posing as an Xfinity customer service rep and they had my info already The red flags that popped up were that when he asked me to verify my info he read it off to me first which was my name address phone number even my email and my credit card number on file which made me wonder if he actually works for Xfinity and is doing inside job scams He tried to get me to pay $140 for a Xfi promo which I don't have and in fact all of my bills are set to auto-pay when I mention that he said our autopay is under maintenance right now I suggest that I'll just pay myself online he said I'll send you a link which he did when I said no thanks I'll take care of it I hung up then he called me back from three different numbers starting with the area code  [Edited: "Personal Information"]

I then got an email from payarc with an invoice for Xfu promo So if this guy doesn't work for Xfinity he somehow has all of my Xfinity account information and as somehow tricked voice search to find false numbers
