Unilever - KNORROX: Poor customer service / product info

I have corresponded (and sent photos) to KNORROX via their Facebook page (https://m.facebook.com/profile.php?id= ********** ********** 6) since 29 Jan 2019.

Simple question: Your packaging do not indicate how to make a basic beef stock, as there are no instructions.

On 18 Feb 2019 I received "...sincere apologies for the delay... Please provide us with your contact details... so we can get in touch..."

On 27 Feb 2019 I sent them my email address (preferred method of contact, as I work and cannot answer my phone at random times).

On 28 Feb 2019 I received a Facebook message: "Thank you for getting back to us, Lana. We will be in touch soon."

30 March 2019: I still have not received info from Knorrox.

To date: I AM STILL AWAITING FEEDBACK. It has been more than 2 months now for an answer on a basic question.
