Called but left no message (because I have an app that makes unanswered calls sit through endless rings even after my phone has ended the call).

This number called me twice, said they were from Comcast when I answered and asked if I would be interested in their new promotions. I said no and they hung up. Called Comcast, and they verified that it was not a number used by them, and most likely a scam to get account and credit information from you. DO NOT GIVE YOUR PERSONAL INFORMATION TO THIS NUMBER.

None

from comcast, and said my current plan will end in Aug. My plan is 39.99, but they told me my plan is 49.99. Then they would like offer me a promotion, which is 49.99 for 50Mbs. I said I want to think about it. Called me one day later again.

Hung up after voice mail picked up.
