IDP IELTS — Enquiry on Results (Re-Mark) after 5 times of taking the IELTS exam in 2020

I want to make a request for the EoR due to the principle of not being told by the email before.

I have taken the IELTS exams for 5 times in the same year of 2020 at IALF Jakarta, Indonesia (IDP Australia partnered). Can you please help me to make a complaint? I just want to do the EoR (Re-Mark) for my Speaking score which has drastically decreased for 1.5 points from 7.0 into 5.5 while my other scores are increased.

This is hampering my admission process in Stanford University and full-funded scholarship program where I have a financial hardship and a budget limitation to take the IELTS exam again.
