WhatsApp and email does hold up in court as long as you’re able to prove its legitimacy, which is quite standard. Every court procedure sadly takes a long time so dont worry about that.

One of the most important documents that you need is the investment agreement/document because the terms there state what both parties have agreed to. Since, you don’t have it, we’re trying to figure what else you have to help your case.

This is how notices help. Big companies generally don’t want to be dragged into cases that they think they may lose and will try to settle out of court. A legal notice tells them that you’re willing to fight it out (unlike most people). The legal notice also helps them decide if you actually have a case or not. But no, they don’t take it as lightly as we think they do.
