It’s not the $1 fee, it’s the ethics.
Seller had a moral or religious reason not to work with my product but did NOT state this on the profile page. Therefore, I had no idea the seller would not accept my gig.
Fiverr.com refuses to refund the $1 even though it’s no fault of mine that seller broke our agreement to perform services.
So the cautionary tale to all buyers is: thoroughly vet your sellers before ordering.
Finally, I am more upset that my project is now delayed than I am about the $1. I am most upset about the broken promise and poor communication from the seller and fiverr.com losing my business over keeping my $1.
