LPT When on a call with an operator/customer service line and they ask something along the lines of "Before connecting you to a representative, would you like to complete a survey after your call?" ALWAYS say yes (even if you don't intend on taking the survey).
At several companies, the representative can see whether you have elected to take the survey after their call - which gives them a large impetus to keep you waiting time short and to be as helpful as possible. They know their services may be discussed in the survey. I typically say "Yes, I would like to participate in the survey" regardless of whether I have time to participate.
