Back in October, I started receiving notifications that said, “You've reached 50% of your Internet usage”. In the past these notifications would arrive by email or I could check my usage by logging into the Bell site, either of which is entirely acceptable. However, in October, these notifications began to appear embedded into web pages that I was browsing, specifically in web pages that don't belong to Bell and have nothing to do with Bell.
I don't care that they provide a way to disable this, or that somewhere in Bell’s terms and conditions I may have ostensibly agreed to this action. They shouldn't be doing this any more than the post office should be tearing open my letters to insert notices that they want me to see.
I wrote a complaint to Bell (and canceled my phone and Internet with them!) but they didn't reply. I also wrote to the CRTC and the Privacy Commissioner. The Privacy Commissioner said it's not in their jurisdiction. I'm still waiting to hear from the CRTC.
