Getting calls about some kind of registration for a new tax. Ridiculous.

I keep getting calls on my cell from this number and have no idea who it is. I don't give my cell number out to anyone other than family and friends so it is strange I am getting these calls. They have been calling every day this week and yesterday they called 3 times.

Its a reminder call from BC gov't to register for your new PST number

They call, I briefly lift the receiver and then hang up, disengaging the ring.  They leave no message.
