Managed to get some tablets added by going into a corp store and finding an agreeable employee who knew what they were doing. Unfortunately that doesn't work with smartwatches. The person in escalations said my plan (PoMC Ultra) was 'expired' and I'd have to pay $10 to add a watch onto the plan. Ended up filing a complaint here https://www.ccts-cprst.ca/ and I suggest others do that as well. This is a blatant bait-and-switch -- they can't just decided to remove features from a plan and then say that they didn't change the plan.
