Well "marilyn", if the calls are coming in from people as obviously unable to deal with the English language as you are, then yes. The calls are scams. As far as scary goes? Decidedly not. Indian scammers are about as scary as an itch on a butt cheek & one that calls from a "Dynamic" number is just plain laughable. Don't even try here "marilyn".
