IDP IELTS — Unable to download eTRF

I appeared in IELTS academic test on 20th November and got my result through Normal message on 3rd of December but still I haven't receive eTRF from website, whenever I click on the link, it shows 404 error. Please resolve this issue. Why IDP make commitments that they will provide the result after 13 days if they can't. And what is the importance of result if it can not be used for official purpose as eTRF is not available. I spoke with customer care executive three four times but everytime they come with different excuses. Such an irresponsible organisation.
