Is the money paid by the juice company as compensation for the presence of mold in one of its products halal or haram?

It is permissible to reclaim the full price of the juice carton, but it is not permissible to take the amount as compensation, because it is money taken by coercion or fear of a complaint, and the wealth of a Muslim is not lawful except with his willing consent. If what the company offered was with consent and willing spirit, then it is permissible to take it.
