Landline Message Waiting Indicator

My Message waiting Indicator has not been working since April 2026. Did not notice until October 6/26. At this time a Telus rep started a work order that didn't solve the problem. Since then and 3 reps later, there was a new work order started. The rep called back one time on Oct.16/26 with no resolution but indicated it was a Telus provisioning issue. He had indicated he would call back in 24 to 48 hours. That was 6 days ago with no call back. He also indicated that if I call back with the same issue a new work order would be started and the process starts all over again. Now what do I do? Whats the point of voice mail if you don't know it's there? Is Telus just side stepping the issue with threats of restarting instead or rectifying the issue that is plainly provided in their literature? Do I contact the CRTC to get a resolution?
