i recieved numerous calls today from this number 1-800-453-2156 but did not answer due to not recognizing the number. they called me at least 12 times so i finally gave in and answered. as soon as i did, a middle eastern accent said its ????? computer company and said "ok ?" i started to respond by saying "k, do not call me anymore" but as soon as i got the "k" out of my mouth they hung up. I heard of this new scam just yesterday where these phone scams get you to say ok or yes and they record your voice, so I think this may be one of them.
