You don’t have any gigs and I don’t see any sales listed for you either. What money would you have to withdraw yet?
I gve some work to someone and they ruturn the money so i have balance $125 in fiverr acount which i trnsfer from my bank
As the Terms of Service mentioned when you signed up, refunds are Fiverr credit. You can spend that on gigs.
but its trasfer from my Bank
You are welcome to contact Customer Support and see what they say. When you spend funds on Fiverr and a cancellation happens, the refund becomes a credit in your Fiverr account. You can spend it on gigs, but it does not go back to your bank.
