The incoming numbers aren't reported in Self-Serve usage history?
Some phones display the actual number while ringing, but only "unknown" or "private" or "blocked" afterwards. It depends on your phone software - if it's a "feature" you must have then your choices of device brand/model, operating system, and apps become limited. And you'll only have seconds to memorize or write down the incoming number before it's erased from your phone display (and user-visible records) anyhow.
You can't use caller ID services like CallTrap in Canada. CRTC prohibits them.
You have the option of changing your number through Self-Serve, once per month if you like, at no cost.
You can send a private message to @CS_Agent and request a "call trap" service. In Canada they're legally required to do so upon request. But they're not required to reveal the number itself if they choose (or have been instructed) not to. Basically if the harassment is from an individual then they'll assist you, if it's from a business (government office, registered collection agency, etc) then they might not unless you escalate into court.
