This boiler room is located in Southern California. I have called several times trying to feign enough interest to get one of these morons to spill the beans as to their address but haven't been successful yet. You can reach them at 866-514-0745 and hit the prompts to speak to a human. Good luck and please post any info you get.
Caller ID said Unknown Name...so didn't answer...caller did not leave message anyway. I checked 800 notes and see this is another scam. Will block number.
You should be able to block the number from your provider's website. If it's a scam I don't think the caller will care if the call is legal or not. Good luck and I hope your father is doing better.
