Contact Figma support by phone (we want to buy it, but we need a contact person)

How can I get contact with Figma team by phone?

We are trying to register Figma as a tool in our company to be able to buy it, but they don’t reply our e-mail for support and it’s getting to late because the project will already start in some weeks and we will need to use another tool for prototyping.

Can anyone from this forum or the support team help me (Eduardo Figueiredo) or Camila Zavan (we already contact Figma by e-mail) to buy the project and register as a tool in our company?

Thank you in advance.
