Got call from this number on christmas day about 3 times, but they did not leave a message. They hung up after my answering machine picked up the call

what are they faxing you?

Hi guys,i don't think that it's Rogers. i subscribe to digital phone service from Shaw and I'm getting at least ten calls a day. yesterday i went out for three hours and came back to 12 calls! i think that i picked up the phone once or twice but didn't push any numbers and they are still calling.

This is GLOBAL credit & collection

a message to this caller " someone is looking for you already" get ready

I'm an international student and obviously have no debts, except for my phone bill thats due.I don't know why they are calling me and how they got my #.very annoying.  I just ignore the calls
