As with most company forums, you will generally find people here posting because they have issues. People who don't have issues and/or great service rarely feel the need to post. As a long time Telus customer I've been generally happy with the services they offer. My experience has been that the mostly likely time you will have an issue is when you make changes to your service.
I think the best thing to do is ensure everything is working to your satisfactation while the installer is on site. This would mean testing your Internet speeds (wired and wireless) as well as the functioning of any other services you may be getting. If everything checks out it's unlikely you will have technical issues.
There have been some reports of billing being different then quoted so you may wish to ensure you get all the details of your service and what it will cost.
I hope that helps.
Just a long time customer hoping to help.
