Xfinity-target promotion scam

Being taken advantage of by scammer that contacts you from number that shows up Xfinity. They have account information that you didn't give them. Sure didn't seem like a scam but after being ripped off for hundreds of dollars, you're told it's a scam. Hard earned money just gone.  Nothing can be done about your money but please post about it and contact FTC. Xfinity knew before the customers and should have sent text, emails and snail mail flyers to warm their customers!  That's what any decent company or person would do.  I am fine with warning others of scams and other things that could be harmful. Especially if we have any type of connection, family, friend, business because that is the proper thing to do, to ensure we live in a decent place.  Why wouldn't you at least warn the people you depend on, of the low life scum that is crawling up out of the stinking sewer from hell, with only one purpose which is to steal their hard earned money. Warn your customers, the people you accept money from for your over priced services to sustain your company. I am curious, will Xfinity be held accountable for not sharing the information. I would hope they are not gaining financially from this scam. They already charge enough for their services.
