Visvesvaraya Technological University — About my PDC issue - 4VM17EE046

I'm Pallavi M and my USN is 4VM17EE046. I had applied for PDC on 27th of October and paid the fee successfully through phone pay UPI ID on 29th of October. And I got the mail that I have successfully paid the fee i.e. rupees 400.
I attached the PDC application form and payment copy.
It has been a six days now but I have not yet received the PDC. So please kindly solve my problem as soon as possible.
