which gig was it just out of interest? without giving names, what is the buyer saying?
i noticed some strange inconsistencies with your virtual assistance gig, where your basic and standard packages come with 7 revisions, premium only 5 but in the description you guarantee unlimited revisions
if that’s the gig in question then you may be out of luck. the view fiverr might take is that you are now contractually obliged ot offer whatever revisions the buyer demands, until the end of time, or the order can be cancelled even years after it was finalized. blocking would likely just result in the order being refunded at your expense
my advice would be to go through all of your gigs and remove any references to unlimited revisions of satisfaction guaranted, as well as any inconsistency (which fiverr will see as false advertising)
i’m not a seller so i’ve never been in this position myself
