IDP IELTS — Poor organizer, not genuine marking

This is the first time I'm taking IELTS with IDP. Such a biased and fraudulent marking. When I have given my exam with British council the marking was genuine. But IDP really worst in conducting exam, not very organised and business making.
Really fed up with the service. People doesn't have any other options to take IELTS other than IDP. These people making use of it. Speaking tests also we don't have option to choose the date.
