"Hi, my name is Antony. I'm here to review your health provider. CAN. YOU. HEAR. ME. OKAY.? After hearing that last sentence I said no then hung up and blocked the call. I've heard of situations where the scammer will try to entice me someway to say yes in the conversation. Then I  have agreed in principle to an expensive service which I could held liable for payment. I've heard that the "yes" will be the verbal agreement which there is no favorable court remedy.
