How do I contact Zaif?

I'm curious about reaching out to Zaif, could you guide me on how to do so? I've heard they're a reputable cryptocurrency exchange and I'd like to get in touch with them regarding some potential business opportunities. Is there a specific email address or contact form I should use? Additionally, do they have a customer support number I could dial in case I have any urgent queries? It would be great if you could provide me with the most up-to-date and effective ways to get in touch with them. Thank you for your help!
