Mobility offer - scam or great deal?

Received a call from 888-519-0122 - said they were calling from Telus. Being polite, and having time, I was curious about the offer - asked about some kind of streaming / mobile plan bundle. Eventually landed on talking about $35 / month / line deal for mobile - unlimited talk / text CAN + US, 5G LTE, etc.

I asked to be emailed the details - he said he couldn't do that (something about competitors getting the info?). Seemed a bit off. So I asked for a call back b/c I was busy.

When he called back, I asked for additional verification that he was from Telus. He read account details (billing details, etc.). These were accurate. He then sent an automated "how to sign up for an e-sim" email that was also legit.

When I call back the number, it goes to a Telus automated menu. However, when googling the number, I came across these two conflicting posts with Telus:

Post 1: It IS a legitimate number (https://forum.telus.com/discussions/mobile_devices/is-this-a-scam/171441)

Post 2: It is NOT a legitimate number (https://forum.telus.com/discussions/mobile_devices/verify-telus-number/174523)

Anyway - I read somewhere that you can ask the rep to post a comment on your Telus account that you can then login to see. He said he didn't know how. So I said that if he can figure that out, I'm interested. If not, sorry.

So - am I too paranoid or appropriately cautious?
