I believed 99% of those are insurance agents. Ask you to do
survey, get your hp and keep calling you to sell their product.
They are targeting young guys and gals, such as NS,
poly...uni...etc. Because most of them do not have insurance yet,
unless bought by parents. They even call your hp on the spot to
check whether it is real or fake. They are irritating, you just
don't stop and keep saying NO...otherwise, good luck to you.
I am old enough, most of the time, they don't bother me....even i
am stopped, i won't entertain them, although might be approaching
by pretty gal
