Unable To Reactivate Workspace

I have paid for 2 x Team plan, then add another 5 members to the workspace, the workspace was deactivated because I failed to pay for the second invoice which OpenAi billed for 2 extra seats but not 5. I pressed for the option to reactivate workspace in my account panel but system kept report payment page error that the payment process could not be started. Issue reported to support@openai.com and ar@openai.com, the only solution was they emailed me a link to pay a stripe invoice for 2 extra seats. Should I pay? I am not sure even if I pay, my account could be reactivated due to their system bug.
