You could take this to Customer Support, but you’re not even including the actual gig copy, which is a bit misleading. To wit, here’s what you description actually says at the time of this comment:
I would report this to Customer Service if you have delivered what you said you have (and it’s all clearly signposted within your delivery under headings or some other obvious flag that corresponds to what you offer). However, you need to make it clear that you do NOT offer test results or screenshots.
Additionally, while you say its a review from the POV of an everyday user, that’s not explicitly clear in itself.
My recommendation is to make your description way more clear and with this guy, you’ve got 3 choices:
a) refuse to do anything and insist that everything was clear (do you like bad reviews? This is how you get bad reviews)
b) contact Customer Support–but with this argument you won’t get further than a “please talk it thru with your buyer” template, which leads to my preferred option,
c) make the screenshots of test reviews etc and redeliver, then make your gig more clear.
Guys, we should all use Photobucket in our replies! It’s clean, it integrates wonderfully and you can dump it anywhere in the post! </photobucket shilling>
EDIT: I realize there’s a contradiction in my CS advice, but think about it like a CS agent. Obviously as general users, we can’t see the delivery and relate it to the actual description, so it’s a case of offering two sides of the coin based on er… half the coin or something. Also, I can’t be assed to edit so this is my justification.
