If 1-2 funds simply stopped replying after almost a week, should we write a review on their Vault profile?

Unfortunately, it is very common for people to go silent (it is always more advantageous for investors to drag it out even if they might be interested. They won’t move fast unless they feel pressure. You can definitely can and should follow up once a week until your round is closed or close to being closed. If following up with them, you can follow up with some sort of update that momentum in your fund raise or customer growth.
They may be having internal discussions, deciding who to talk to next, making intros, etc. The biggest key is to keep filling the top of the funnel with more meetings. Remember, for every 100 meetings a partner takes, they probably make around 1 investment.
But yes you are able to leave a review for any person in the vault by going to their profile.
