They left no message when they called every single day. I called the number back today and a message from Comcast answered and I held the line. An English speaking female answered and I told her I wanted to be removed from the list. She was very nice and said that Comcast adheres to the do not call about promotion preferences you request and removed my number. She said it could take up to 30 days before no new calls would stop completely. Said to call 1(800)Xfinity with any questions about this call. Thanked me for calling and told me to have a good day. She was very polite and she sounded like someone from the US, not China or India.
