IDP IELTS — trf not received

My passport no is a50044668, i am having an international passport. I gave my exams on 11th jan and haven't yet received my trf. I wasn't intimated for a week and later when i inquired i was told my photo is unclear. I explained that due to the emblem sign on my photo being colourful while scanning the passport, the photo gets blurred. I have been after these people for almost 2 weeks. Still no responss from them. Have you never had international candidates? Is this how you work? Harassing candidates mentally??
