Everytime (twice) I have contacted Square Enix store support (merch and stuff) they have sent me a proper satisfaction survey.
I wish they cared that much about how happy I am with their game. What's the point in a great store experience, to keep me coming back, when your game means I will 'not' be coming back.
That select your reason for cancelling sub question is useless. I don't. see how they can formulate strategy based on that.
They really ought to put some effort in to capture the reasons in a way that gives them a chance on having something to act on.
I would by now expect the cancel questionnaire to reflect dune if the things I have seen time and again here.
Or maybe even a 'may we contact you to follow this up?'
