Indira Gandhi National Open University — degree not yet received

I had graduated successfully in 2015, and paid for the degree certificate to be received as well. I had provided a different address for it to be mailed, since i had relocated. However, even after more than a year, ignou has still not sent me the degree certificate. The delhi center says the regional center has the degree certificate. The regional center says they have already mailed it to me old address. The post office at my old address say they have not received anything, neither has my residence association at my old address. Now delhi center says apply for a duplicate degree certificate by filing an fir, etc. Is this fair? I have copies of all emails that i have sent with all communication to them. They are just giving us the run-around for a degree that has been rightfully earned. Please help!
