Do not use them

In hindsight, I should have checked HalloPeter first before registering with IELTS. The written test doesn't allow you to finish early when you are done, you have to wait for the timer to run out. I raised my hands a few times in order to ask if they can end the test and the proctor did not answer me. Before the timer ran out, the internet connection dropped and I could not get back in on time. I emailed them immediately afterward to ask if they can mark where I got, it because I did finish the test. I was just waiting for the timer to finish. They refuse to do it.
