Help!! My University's mistake may get me into trouble...

I have just graduated from my law degree- upon results day I found out I got a 2:1, great! However, upon opening my transcript at graduation my certificate said a 1st class, whilst my transcript remained as a 2:1. This happened to some of my friends who, like me were close to getting a 1st class by a margin of 3% + also we all partook on a study abroad.

Here's where Im stumped, my university professor said that was an official 1st class as it has the stamp, seal and signature- however, it is the exam board/ student admin team who have the final call. I have tried calling up and emailing my university and law school to figure out what is going on but they have not been much help, everyone who I have spoken to all seemed just as confused and are telling me to wait 2-3+ weeks, but I cant do that, I have applications to submit!

So now Im not sure what to do- integrity and honesty is key to the legal sector in which I want to be a part of, so I do not want to mislead prospective employers. I know by saying a 1st class I might have a higher chance at securing the role and to be honest thats what it says on my official university llb (hons) law certificate, however, Im scared that if i say this, my university would turn around and say "actually you have got a 2:1" and i would have been misleading in job applications.

This is honestly quite annoying and such a sour way to end university, what makes it worse is that no one is really being of help- there have been no letters, emails or any communication offering an apology and trying to rectify the situation, all the contact I have received was through me reaching out first. I can appreciate due to it being the start of a new academic year that everyone must be so busy, I know I run the risk of sounding self centered but I really would like clarity on my actual grade as soon as possible.

Is there anything I can do? Has anyone been in a similar situation?
