After calling, supposed Comcast customer support or marketing agent picked up immediately and asked questions about quality of service and what I watch. Knew my name and address. This number had called me several times for the past week or so but no message left.
I've gotten many many calls from this number in the past month. Today I received 2 calls from them. Every time they eitehr hang up when I answer, OR if I don't answer, they never leave a message.
