Rang twice. I did not answer and no VM was left. Never answer any call where you do not know the number and they never leave a VM. Block them if they do it again.
Called cell but did not leave a message. I called number back and it has a recording stating: Hi, this is Julie with the award redemption center...you have recently visited one of our sites. I then hung up... Its spam.
Received call from this number but it only rang twice. I didn't pick it up.
Calling back number reached recording of friendly "Julie" with the reward redemption center.
Now I've blocked this number.
