How to deal with this?

I got a 'review' that's not really a review...
It was more like a support question...

I would like to know how should I deal with a review, that's not relevant, but it affects my product rating.

it sucks but you'll always get a review or two like this even if your app is perfect. I'm not sure if people can re-rate or anything but help them with their issue and ask for one if possible. Either way, try not to be passive-aggressive and act like all you want to do is help the guy with his problem and your customer service just looks better for it and it won't put anyone else off who saw that someone had an issue.

@crazyoldgoat1 thank you for your reply.
After sending the solution on private, I never got a reply back from that buyer... : ))

At least he's happy ) ( I hope )

Some people, eh? Well maybe send him a follow up in a day or two to check things are going smoothly and asking if he could reply to the comment and say so because it would help you out a lot.
