Got Same call at work and cell. Tell a manager to tell them not to call your work or they will press legal harrasment against them. Nobody even bill collectors are allowed to call you at work. if you look up # it is a house # under 10 different people. and ICS is out of Canada! My lawyer said ignore it and they will go away to not answer to any numbers you do not know it can go to voicemail.
I got the same message as well. They even had the last four digits of my social security number, and they knew where I worked. The man that called said he was from International Courier Services.
Adding on to the post above... They also asked that my manager be present as witness, and that if I wanted to set up a more convenient time for delivery, that I was to call the number back! I believe the call is coming from a cell phone!
