Singhania University — Completed my degree course and paid all the fees yet certificate not being issued

I did a course on BEd Mathematics and completed it last year. Till now I'm behind the management to issue my certificate but there is no response from anyone. I have paid all the fees and everything. I have one Shobhana Thakur's contact number but she is very rude and harassing me. She isn't even telling what I'm supposed to do nor picking up my calls. I cannot find my enrollment id registered on the university's website also. Fell like I'm being cheated. I have paid a total amount of Rs. 33000 till now.
