It’s been 6 to 7 Months I am working on Fiverr I faced this issue only 1 time when I had 1 Cancellation and after that I worked really Hard and my all the Stats are completely 100 Percent I have Completed 150 Projects and only 1 Cancelled and two 4 Stars only. My all the Gigs are Ranking on first Page on my Main Keywords. So I think it’s all about the Performance of your Gigs. I usually Respond to my clients in just 2 to 3 Minutes or even in 1 Minute lol.
