I believe that updating the gigs. i.e., their titles, description, image could help in boosting it....So, try to change the overall gig and wait for the results...
Also, I would advice you to make more gigs related to your niche.
You haven't made a gig yet and expecting someone to order you? How is this even possible?
Create some amazing gigs based on your skill set, be online and if you still don't receive the order in 2-3 months, then you can complain
Why Are you even paying to buyer? Was he threatening you?
In any case, contact customer support and don't involve in the activities that could result in the permanent suspension of your account
I believe that you should focus on changing the gig image, for sure.
Try to focus on the stuff which is important and should be visible to the buyers at the first glance. Focus less on the text.

If you have some orders in queue, it will not affect your ranking else if you leave your gig empty for several days, there are highly chances that it will be deranked
Brief feature needs a lot of improvements.....I have some friends with amazing Fiverr profiles but they don't receive quality briefs. So, the match is not exactly according to the niche.
Sometimes, there are requests for coding, even if you are offering Shopify dropshipping services. I understand that Shopify dropshipping lies in the e-commerce development but it doesn't cover custom coding.
Overall, this feature is beneficial but needs a lot of improvements
I recently made a post on it. Unfortunately, it is a trend on Fiverr to make false promises to the clients, just for the sake of getting orders. This technique surely doesn't work in the long run
