Singhania University — Hard copy result and degree certificate not received

Sir,
I have complete my BSC AME examination in December 2019 . Till date I have not received the hrd copy of the result and also the degree certificate. I have sent numerous email and also tried connnecting ion the phone.
They keep moving in circles, university ppl saying contact the center, whereas center suggest contact university.
All the required formalities have been complied from paymnet of complete fees to submission of documents.
Additionally the staff at Mumbai center is so rude that without listening they wil just disconnect the phone.
