Reg D / Private Placement | bootstrapped to funded transition

I'm dealing with a situation and need some guidance.

bootstrapped to funded transition. I've been dealing with this for about 5 weeks now and the situation isn't improving.

I have already done some research online but the other party is not cooperating.

What are my legal options here? Is it worth pursuing?

I dragged my feet on getting legal advice and it cost me. Don't be like me lol
