I screen all my calls. I never answer the phone unless I recognize the number. If the call is not important enough to leave a message I will not answer it and this number 516-453-6837 did not leave a message. They are definitely scam artists using 516-453- numbers. They are not sensible people they are just rude a##ho#es trying to make a commission. Something should be done about this, but I refuse to talk to these people since they will try to ruin your day if they do not get a commission.
