Is this a SCAM???

[wireless]

I'm very confused right now. Today, I received a call from 833-390-3721, claiming to be a representative from Telus. Because I had only switched to Telus a month ago, I thought they were calling to ask for feedback on my internet service. I wasn't sure if they were scammers, but they provided detailed information about my internet plan and account balance. Then they asked for my SIN number, and without much thought, I gave it to them. Later, I received another call from 844-962-1419, which was also from the previous representative. She mentioned that she hadn't asked for my date of birth yet. After telling her, I realized immediately after the call that I might have been scammed. I promptly informed my bank, TransUnion, and the Canada Anti-Fraud Centre. In less than an hour, I received an email from Telus with the following email addresses: telusservice@i.telus.com and noreplyteluschannels@telus.com. I also received a text message from 777222 saying that I had successfully selected an Optik TV plan. This text message left me very confused because the same number was used when Telus installed my internet previously. I checked my Telus app and indeed, I had activated this Optik TV plan. So now I'm very confused whether this is a scam or a legitimate promotion from Telus. Do they usually ask customers for their SIN numbers?
Thank you.
