Ok I knew it would have happed soon or later.
I decided to not support an item of mine anymore and a user asked me for support just 2 days ago (during a non working day).
I have not replied in 2 days and I got 1 star with this reason:
no support at all , plugin did not work - useless
“No support at all”: really??
“Plugin did not work”: Uhm that’s weird because the plugin was sold 549 times and rated 4.27 (counting this 1 star).
So what should I do? Should I give support even if the user have not bought support?
This is not fair in my opinion.
