I think this is what happened! I think Rogers sold their cell numbers as I am surrounded by 3 roger cell phones and all have been harassed with 1 call per day. The telus and Bell haven't been called... yet.
Exactly the same call - "This is the second warning about your car insurance (or warranty or something). You are currently uninsured... etc."
I've had this call 4 or 5 times now though... getting a bit sick of it to be honest.
