Someone else's TELUS TV+ profile has overwritten mine, serious account linking issue?

A couple of weeks ago, a relative signed up for a new TELUS TV+ plan under their own Telus Home Services account (separate email, home address, and account numbers). Unbelievably, on the very same day, my existing Telus TV+ profiles were replaced by the two new profiles they had just created on their own. Mine ceased to exist. We have completely separate account numbers, different email addresses and independent login credentials! Whenever I log into my tv with my email I see the same new profiles that they see when logging into their account email. According to my searches this suggests some sort of backend account linking or provisioning error, which raises obvious privacy concerns. How can two independent customer accounts end up sharing TV+ profile data? Did they base it on the same last name or something? More annoyingly, it overwrote my favourites and watched history. Has anyone experienced anything similar, or can someone from TELUS explain how this could happen and investigate? Very frustrated with Telus and their constant account issues, it gets worse every year.
