Existing customer promotion
I just got a phone call, supposedly from Comcast/Xfinity, offering me a reduced monthly bill for the next two years if I paid 4 months in advance. They gave me a phone number of 888-203-6795 for the "Billing department" to call and verify that the promotion is real, and they gave me a code to present for getting the promotion. Is this the real thing? I can't find that number listed anywhere for the Comcast billing department.
