Linking bank account

Description

I’ve never had an issue with accepting money before until now. I have a decent amount of money to claim but when I go to claim it, it says to link my bank account. When I try it says I don’t have enough information so i don’t know how to get my money. I’ve tried to call but I can never get talk to a real person. I only have a few days until the money gets sent back to the person and I’m not sure what to do
