After Submitting the query, I received this Answer,
"Hi there,
Thank you for reaching out to us about this issue. We understand you tried to open a Seller profile on Fiverr, and received our response explaining your request wasn't approved.
You're welcome to continue using Fiverr as a buyer.
If there is anything else we can help you with, please let us know"
Since then I have asked them what the exact issue is. So, that I can resolve it, but I didn't receive any answer from 4 days.
