Target Scam

I just rec'd a call for 50% discount for 3 years if I pay $780 in target gift cards up front and then it will revert to my normal billing.  FLASHING RED LIGHT

Problem is the math does not work.   My monthly bill would be less than 50% at $65 a month for 3 years yet the entire con job speaks about a 50% discount.   MORE FLASHING RED LIGHTS

My concern is he knew my monthly bill amount as well as my home address and phone number!!!!!!!!!!!!

I think Xfinity has had a security breach that needs to be addressed immediately.
