IDP IELTS — Providing no solution to my complaints and the contact number is also not working from last 7 days

Hi
I transferred my exam from pen-paper to computer-delivered for general training, but when I switched the exam it got covered in an academic training I write this whole case to IDP but haven't got any solution yet. My exam date is 17th May 2021. For last few days, I am also trying to contact the helpline number which is currently not working so I am worried now if this problem gone solve or not.
My complaint ticket number is -[protected].
Kindly help me out with this problem as soon as possible.

Thanks and regards
karan
