The same situation I have at this moment. Enrolled to the program => no feedback. I paid with Revolut card. Then I raised the incident 102265552946 when the period is over + a week => no response. To be honest, I have never imagined that it would be so with Apple Organisation.

The same situation with my request. Paid with Revolut, EU, LT. Raised the incident 102265552946, but not any response.
