I went to the university (UPTU Lucknow) in Nov 2013. I had a terrible experience there. I saw a lot of student s at the reception and a guard preventing those students to enter the room where the registrar sits.
The authorities didn't allow me to go inside and talk to anyone on the first day. On the second day, i went to the guard and told him that i want to meet Mr. <XYZ> who was working on some higher post in the university (i didn't know him i just heard his name on the first day). The guard allowed me and i saw the registrar himself telling the guards that "None of the students should come upstairs". I spoke to a clerk there and he said it will take another couple of months to get my Degree. Then i saw a bundle of degree certificates lying there in dust. I asked him to check those and while he was looking at those degrees, i saw my degree which had "Incorrect" name over it. I took that one only.
Sachi, let me tell you, you have to go to the university to get your degree. Calling them over the phone is not going to work. Moreover, get one affidavit from your college confirming you were a student there and the university people can handover the degree to you in person. With these documents, you can go to university campus (sitapur road, lucknow). Honestly, i do not think they are going to help you but it's worth trying once or twice.
I hope you have collected all your semester marksheets and provisional certificate. These documents atleast prove that you have done B.Tech.
