thanks for the reply, I have already kind of tried option 3 but they just gave me a lame answer that they'll give it to me after the 3 months
Sadly, unless I'm misreading the situation, the relationship is likely broken enough that you wouldn't want to continue with them. You'd be either going it alone with your codebase or asking them to buy you out, subject to you seeing it through to launch, perhaps?
If you can negotiate a payout rather than equity, it might be a better return given their networkers aren't networking.
I agree with everything else, it's very unlikely to work out.
It only takes 5 mins to type out a letter. If they blow you off you know you are getting shafted.
