Bruce, when you dial the number, their voicemail says York University.
They call me over and over again even after asking them to stop.

I get this number calling 3 times a day - EVERY DAY. Just like clock work 1:15, 1:40 and 9:16pm, even on Sundays. When I try to call back the mail box is full. If I answer, they hang up. FED UP WITH THEM. Anyone have an idea who they are?

I was told it was from York University.

They called around 7:30 PM and said absolutely nothing while I said Hello repeatedly

Just got a call from this number.  This time it was to update Health Card information.  So don't please don't associate these calls with any reputable organization (like York U.).  They appear to be phishing for information and will (apparently) use any angle to get you to divulge it.

They call me a few times each year. Even after I told them not to call me anymore! Annoying!
