eCIR Exam New Exam Voucher for Retake

I have take it eCIR exam last year and 2times failed with below feedback from examiners.

Failed due to unauthorized collaboration/use of unauthorized resources. You ARE NOT ELIGIBLE for another attempt.

This year I bought again and I will retake it.

But this time also just want to confirm that I can take it exam or I am no more eligible for retaking exam?
If not eligible how can i do for new purchasing? Can I change other exam like eCTHP ? eCPPT ?
