If the user is unhappy, leaving a review won't make them happy. Providing support via some other mechanism to try and fix their issue, that's what makes them happy.
If the user is already happy, they don't need support. But maybe they'd like to leave a review to tell other people that they're happy.
The ratings are not for you, or the customer leaving it. They are for other customers. The problem is, you think something is for you, that is not for you, and you are asking for everyone to behave like it is for you, and you are telling them that, if they don't treat it like it is for you, that you don't want them as a customer.
Fair enough, if that's the way you feel, but if that's really what you want ... put it on the app page, not some off-store forum. I question your sincerity.
Reviews are for the customers, yes. But if a customer has a problem, leaving a bad review does not help that customer. And if it's a problem that can be easily fixed, it doesn't help other customers either. Directing people with problems to internal support is unambiguously a good thing. If that customer's issue can be resolved, that's the best solution all around. And if it can't be resolved, well, the user can still go leave a bad review if they want to.
