Bharathiar University — Delay in receiving my degree certificate

This is Sindhu. P. (Reg No: Ph.D. CB-DEC[protected] Psychology). I completed the Ph.D. course in the year 2020 February from Bharathiar University. I received the Provisional degree certificate on 21st May 2020. Since, it specified in the provisional certificate that the course was completed Part-time, most employers are not willing to recruit. This was one of the major reasons for requesting the original degree certificate.
However, my expectation as an ordinary student has become unrealistic due to the outbreak of the Covid -19 Pandemic.
The University was adamant to provide degree certificate only after The Convocation Ceremony. The convocation was held on May 2022 but I could not attend the function due to my personal reason. I informed the University to send the degree certificate via post and paid the fees involving the same. I paid the degree certification fee of 1000/- on 09th November 2020. and they received it on 18th November 2020. And after the convocation was completed, I was asked by the University to pay an additional due payment of 600/- on 11 July 2022, which I paid on the same date. I am still waiting to receive my degree certificate. When I contact the University, there is no response from the University whether they already sent the certificate or not.
It would be great if you could extend a helping hand to the students who are living with the hope to get the certificate and apply for a job based on that.
