They do indeed phone you. Someone I know owes quite a bit of money and used my phone number as their contact number. I used to get calls from BC Medical two or three times a month because of this.
Yes Joe is correct. It's the British Columbia Medical Services Plan Collections. If you get behind in your MSP Premiums you get an automated call from them reminding you of your not being up to date with your payments. What a Bother!!
I didn't pick up, but I called MSP, a 1-800 number on the gov website, and they said my account was in order. They called after 8PM as well. Seems strange that a government agency should call after 5PM.
