I called the number back and got a "senior publicist", no company name. I hung up on them like they hang up on us. Don't know why they bother calling when they just hang up on us. But oh well, they sate blocked now.
Just got this call.
They claimed to be with some "publisher" and said I signed up with an "online partner".
She was polite enough when I told her that was not true.
At least she wasn't rude lol.
