Consumer Redressal

I had given an application for granting transcripts for PG DIPLOMA course from Karnataka state open university(KSOU)Transcripts r required to send to universities abroad.I payed Rs 8000 for 2 transcripts. The KSOU authority sent only PHOTOCOPIED marksheet SIGNED BY REGISTRAR.I recvd it after 2 months and only 1 single copy.Those documents are NOT transcripts.They are plain photocopies signed by registrar which is not acceptable abroad. Now,I have asked them for a refund. But they are asking me to send everything back and after that they will refund Rs 8000. I have wasted so much time and money and at the end I am not receiving the right documents and also no assurance that the money is going to be refunded. Only to send the signature on my marksheet they took 2 months. I cannot trust them that they will refund my money! If i send those signed docs I wont be having any proof with me! Please help..I have emailed & spoken to the registrar and Vice chancellor PA. I do not see any hopes.
