Hypothetical question

EDIT: added more context below. Has anyone dealt with something like this? I'm not sure what my options are.

ghostwriter wants credit. I've been dealing with this for about 14 weeks now and the situation isn't improving.

The contract was signed 3 months ago. I have a copy of the original agreement. The total amount in dispute is approximately $46,000 🤷.

Has anyone been through something similar? What worked for you?

Every time I see a post like this...

The #1 mistake I see here is filing with the appropriate government agency. I'd recommend gathering evidence first instead.
