Have you tried contacting their representative on the forum ->
@StunnaAlso, did you reach out on their X account
[HERE] or the Stake forum
[HERE]?
We hope they can help you by conducting a manual review to search for the UTR numbers in their system.
Anyway, don’t lose hope. If this is an issue with the API, payment gateway, or the platform itself, they should fix it and sort it out to maintain their reputation.
Send your username to him along with any links or screenshots, or other evidence to support your claim.
