Annamalai University — I need my certificates, University taking me for a ride

I have tried obtaining my degree and marks sheet from Annamalai. I live in Hyderabad and the university is in near Chennai. I competed my Distance education and I have passed the exam and also cleared all the fees. I have mailed them the payment receipt and now they are asking for nil arrears certificate. I contacted the Hyderabad office and they are telling me to go to the Chennai office to get the certificate. It's the 4th time I went to the office and they are not taking responsibility. Please give me my degree and transcripts. If I wanted to go to Chennai I would not have opted for distance education
