Have also been getting these calls every 5-10 minutes for the last hour... Just called again as I am writing this, I answered and didn't say anything, waited until someone said Hello?? They wanted to speak with my "IT Manager" I said no and told them they needed to stop calling this number as they have been calling every 5-10 minutes for the last hour and this is a busy medical clinic and I don't need to be dealing with calls like this. She apologized and said she would take our number off of their list. I have also been getting a call from 905-233-2278.
This caller calls every hour and hangs up. I called back the number and got connected into another phone conversation where they can not hear me but I can listen in on them. They are discussing a survey about the radio.
