Rang once then hung up. Usually happens Right before I get this lady that acts like at first she doesn't hear you and then starts talking and never stops. Apparently, Computer generated telemarketing voice. Heard same thing many a times from many different numbers.
Anyways, the first number that calls pings your number back to the telemarketing place to tell them that you phone is active and that you answered the call. That is when the call you back. Never thought the Marriot (or claim to be) would stoop so low. They call businesses that have Employee who need to answer there phones. Genius. But messed up!
