Hello! My name is Heaven and I am currently studying software engineering. I started freelancing on Fiverr on July 2021. Everything was fresh and customers came in with some effort. Quite recently, I lost all of them. No new customers coming. My gigs don't even get recognition anymore. I tried SEO, I tried editing gig images, I tried writing all my info more professionally but nothing. Since the buyer requests are gone too, I have no further hope. I can't start on other freelancing platforms too since I invested a lot on here. What is my problem?

Greetings, I am Heaven. I create NFT art for living. A month ago I had a client who requested me to create 10k NFT images with metadata. My full price is $1000 for this package. The price was to much for them so I asked for $600 and 10 NFTs after the mint. We made the deal and I created the files, made the delivery. I asked them to check and they told me they were going to so I waited. The order was marked as complete and they never messaged me so I asked again. They again told me that they were checking it. Then they never came back. A month later, today, they reached out to me and told me that there was an issue with my metadata and they told me to give them $250 or fix the problem. I have been creating collections for clients and never faced an issue as such. And since I am not a programmer, I use a ready to go program as the generator. I tried to help them as much as I can. I have sent them layer files but they asked me to refund them $250 so they could hire a person to create metadata. Though, since it has been a month I cashed it out from the Fiverr so I am not able to pay them. In normal settings, I ask for extra $10 when it comes to metadata, you can check it on my gigs. I contacted fiverr support but nobody answered yet. However the time is limited since they have to make it ready to mint in 10 hours or so. As an artist, I feel extremely pressured and don't know what to do. Can please someone help me? Sincerely, Digital Artist Heaven.
