Scam

I received a telephone call yesterday from a Xfinity representative who was offering a two year substantial discount on my current plan.  I am fairly certain that this was a scan.  As the conversation progressed he was asking for a credit card number and the first five digits of my social.  I told him I was not interested because there were so many scammers out there.  He gave me his name Steven Fuller, but was obviously from India from his accent, and gave me a badge number!.  He said it was called  affordable internet essentials for seniors.  Sounded like a scammer to me!
