Workspace Deactivated - Payment Issue

I have a business account with 5 seats which I recently (29th April) renewed for another year. On Monday I added a new seat which I forgot to pay for. Yesterday afternoon I received payment link with a deadline of 17th May. The link throws Void error. When I tried logging into my account, it showed that the workspace was deactivated and to activate it I was prompted to pay for at least 5 existing seats. I tried reaching to support on email, but they did not understand the issue and were not able to help me. Please suggest what to do. #payment #billing #deactivation #newseat #voidpaymentlink #workspacedeactivated
