Idp Ielts — Obection on EOR

I am an IELTS candidate who requested that the writing module of the test be re-marked. I received my IELTS EOR (Enquiry On Result) and I found fortunately that the band score awarded for my writing has changed from 5.5 to 7.5. I was really surprised and I thought due to my bad handwritten I already got 5.5. Therefore, IRSAFAM (institute name in Iran which is under supervision of IDP Melbourne Australia) refunded my EOR fee. After two weeks when I requested to receive my IELTS Test Report Form (TRF), suddenly I faced there is a problem in this regard and finally IDP informed me (via IRSAFAM) that my score won't be changed without any EXPLANATION or EXCUSE. My full name is Roxana Aryazand; Test Centre: IR20-Irsafam, Tehran, Iran; Test Date: 10 December, 2016 and Candidate No: 010777.

I participated three times in IELTS exam in IRSAFAM institute. For two last times, I got 6 and 6.5 scores in writing skill, but unfortunately, I could not achieve 6 per each skill that is mandatory condition for starting immigration process to Australia. Third/last time (10 December 2016), I got 6 or higher in speaking, reading and listening except writing. I need just 6 but received 5.5. So, I sent EOR for rechecking of my writing module.

I have not enough time and energy for again IELTS preparation and exam. Honestly, I lost my time and energy during this process and failure that is occurred by IDP. Based on my birth date, I am able to complete all required data/documents which requested by ENGINEERS AUSTRALIA and AUSTRALIAN DEPARTMENT of IMIGRATION by end of next six months. In addition, I paid a lot of money to lawyer and migration agent in order to speed up my immigration process when I received my positive EOR. Now, they won't refund related fee and I am not able to recover myself to achieve required IELTS certificate in this short mentioned time. Now I am really nervous, motiveless and disappointed. I don't know how I can convince myself to proceed anew.

This is so strange that such a big failure occurred by IDP. I saw in EOR that all test papers are marked externally by senior, certified staff and result of this process is final while IDP changed 7.5 to my previous score 5.5. Now, I look like the person whom sent proudly and courteously to top of mountain and suddenly fallen down.
I want to know who is responsible in such strange case and is there any responsible authority that attends to this matter? I read disclaimer section in EOR that is issued by IDP. But I think, it's fair in no way that IDP mistreat with candidates in such irresponsibly manner.

Best Regards,
