Calls once or twice a day for past three weeks, never leaves message. Answered once and got a silent line. Caller id is GRAVEN DRA, a telemarketing firm from Colorado Springs trying to sell free magazine subscriptions. Also uses another number on alternate days: 320-318-4107. Others report this is a number harvesting site so do NOT call the number back- you'll be asked to submit your phone number for do not call registry- they're probably selling your number to other scammers.
