Thank you for posting, ​@Ethereal_happiness1f4b.

I understand how frustrating it must be to encounter the same billing error repeatedly, especially after trying multiple accounts and being unable to start the trial.

I checked the account and can confirm that the trial requests were not successfully processed. Since this issue will require further investigation, please contact us directly for help with reviewing the issue and placing your order:
