Plans Expiring and no communication

I believe there is usually some communication in the monthly statements near the end of the term. Normally it's a good idea to write down the contracts you're in so you're aware when they expire. No company has the resources to call every single customer to tell them their contract is up and I doubt most customers would want an unexpected email advertising new packages. Telus isn't allowed to start you on a new contract without your permission either. 

Complaining to customer service will not serve any purpose besides taking up more time on the call. There's nothing the front line workers can do about it. People complaining or venting is one of the biggest things that leads to long call times to begin with.
