Continue to contact Fiverr customer support. Let them know that you are still interested in verifying your ID and continuing to use Fiverr. You may want to try contacting them through different channels, such as email, social media, or live chat.
Provide additional information to Fiverr. If you have any additional information that may help Fiverr verify your identity, such as a new driver's license or passport photo, or a utility bill with your name and address, you can provide it to them.
Ask Fiverr for a manual review. In some cases, Fiverr may be willing to review your ID verification request manually. This may be possible if you have a good track record on Fiverr and have not violated any of their terms of service.
