Need change Reseller Partner for our account. HELP!

Hello!

We have account with current Business plan and it is locked to Reseller Partner for Billing and plan changes.

Our company should make procurement of Zoom service in accordance with the legislation on procurement. And the winner of the tender are not current Reseller Partner.

How can we unlock our account from current Reseller Partner ?

Zoom support didn't respond to chat and emails. 😞
