Internal referral discount vs upgrade plan?

my experience with telus is below : 

I have just been entertained (nightmare) by Telus Sales Agent - who got me signed in for Home Security and Black Friday Mobile (5 lines) deal. On words/verbal - he got me a 37 CAD Home Security deal (never told me that it was 5 Year binding contract) and with way less devices (on actual as compared to what he told me verbally). Anyhow he also got me signed into a iPHONE 13 deal with 100GB package (with my 5 lines) with 50 CAD for first line and next at 45 CAD Each. But once I signed and called actual Telus - they told me that my signed deal is different from what I am telling them (or what Sales Guy told). After lots of struggle - I managed to got all the services cancelled.... without even using it for a single day (with in 3 to 4 days of signing)... but today i think my nightmware is starting - i got a bill (for mobile only) as 432 Dollars and payment should be done before 28th of Dec 2022..... what ??? but I never used your service ? never got any SIM ? neither any mobile  ? what is the Bill for ? I am now calling Telus and for last 55 Minutes - on wait .. and there seems no end to it ....

isnt it a nightmware ..... TELUS .... what the hell ? All Telecom Companies in Canada simply Suck...... we should ask US companies to take over ....
