IDP IELTS — headphones used in the listening test.

Address: Hyderabad, Andhra Pradesh

I am subramanyam vemavarapu, i have given an attempt for the ielts with idp on 13 feb 2020. I would like to complain how idp people are less taking care of test arrangements. Because of their poor arrangements i lost my band score in listening. I got 6.0 in listening and this is the worst score than i expected. I was changed many headphones on the test date. But no one is working fine. The voice coming out from the headphone is very low. It may be the cause of headphones or voice software.
I have seen good voice clarity in british council test but here in idp it is not. I have lost my test fee because of their careless arrangements. I want my refund back of 13400 rs or another test attempt with good arrangements.
Thank you.
