IDP IELTS — didn't receive ielts trf

Address: Ernakulam, Kerala

I gave ielts exam on november 10th 2018 and my test result was published on november 23rd 2018. Today is dec 11th 2018 and i still did not receive my trf. I contacted with idp several times and by several means (Toll free number, chats, in person went to their office), but still no use. If i don't get trf soon then i'll loose my admission in the university. Idp had assured me that they will dispatch my trf by 11th december 2018 but they didn't do as said.
