Number called mutlple times on a Saturday Evening asking for someone in my family.
When asked about what this was about, they said "comcast billing". Tried to inquire further, but caller became rude and hung up.

Called again one second later asking for another person in my family. Very rude and extremely suspicious.

I have no idea how they got our number and our names. Will be reporting to the FCC, because the call was unsolicited and suspicious.
