Lol, first time I've happened upon a deal that (sort-of) incentivises switching away from an energy provider.
I recently left Alinta Energy, and just received and completed an exit survey which promises a $20 gift card, delivered by email, upon completion of the survey.
So if you were thinking of leaving Alinta, here's a catalyst for you.
It does make sense to a certain extent. Alinta Energy wants to know why you left its service, but why should you, an ex-customer, waste your time to complete the survey? So it gives you $5 in exchange for your feedback.
