IDP IELTS — result withheld and not declared

Address: Gurgaon, Haryana, 122002

I have given IELTS general training exam on 2nd June 2018. My result was expected on 15th June (after 13 days). On 15th June, I received an email stating that my result is under scrutiny and have been forwarded for further investigation.
After 3 months - I received a letter stating that after following strict quality measures they have decided that my result cannot be declared and TRF form will not be given.
How can they play with candidate's time and effort. Without providing any evidence how can IDP state that your result can't be declared. They should provide a proof stating what was went wrong and they are penalizing the candidate for the same.
