it wasn't the best thing you could do, even if you're convinced to the contrary, you can't treat customers like that, plus you can get yourself reported which may result in a suspended account
however i can understand you at the same time, that's why i only have push button gigs which doesn't require more than 1-2 minutes to deliver, so if a buyer asks for a refund, i don't care much and i do it w/o thinking it twice
why?
1. it doesn't worth the time you need to put into the dispute procedure
2. chances fiverr doesn't decide on your favor, so you wasted your time
- order gets cancelled by fiverr, buyer can't leave feedback
3. if fiverr decides on your favor for some odd reason, you'll have your $4, but buyer can and will leave a negative feedback, which is the worst thing that can happen with you on a place where people decide upon feedback
- order marked as complete, buyer can leave negative feedback
you can loose 3 things with disputes:
- time (always)
- money
- reputation
and 3-4 hrs work for $4? i don't think it's worth at all regardless which side of the planet you reside on
