Keep calling and not leaving messages. They call 4 to 5 times a day - everyday. If I try to call the phone number I get an answering machine saying this number is disconnected. Caller id says "World Travel"
I've gotten more and more daily calls from this number, Denver identified. I've been picking up, but not saying hello, which is what evidently activates the robot - thinking to annoy their system. They then disconnect. Not going to bother any more...just blocking.
