Hello MALACHI BAKER,
So, with this mount from what I can see mounts the transmission. This is exactly where they would have been working. This mount in particular is very sturdy and hard to believe it just broke. I also find it hard to believe that they didn't notice that it was broken if it indeed came in with the issue.
They would have had to pry up on the engine maybe or they set up the lift wrong and pushed up on the motor.
Here is a video from Hayne's showing how this axle is supposed to be replaced just for your information:

As you can see there would be no reason to have to move the motor. It's a pretty easy job.
Also, I can't understand how they drove it out of the shop and didn't notice the broken mount. I mean you heard it as soon as you started to drive away. To me that seems like someone made a mistake, broke something and tried to hide it.
You can get the part cheaper if you go to Nissan's official website for parts:
https://parts.nissanusa.com
The part is around $300-$400 Retail.
I found this as a part number for you:
112204BA0B
However, to make sure it is the exact part I would go on this site and put your VIN in to either get the part or at least the retail price.
Also, the labor time to replace this part according to Nissan is:
1.7 hrs.
I would strongly advise not going aftermarket for this type of part as it may fail prematurely.
With parts and labor, the job should be around $600-$700.
So, to answer your question I think someone may have broken it accidentally, but it is hard to tell. I would take a look underneath the engine or the transmission especially and look for any tool or jack marks and take a photo of anything you find.
One thing I will point out is as a technician you always keep an ear out for noises, vibrations, anything. They would have had to test drive it after doing the repair so they would have heard the noise. Also, these guys at places like Firestone get upsells, so if they find another repair that has to be done and the service advisor sells the work, they get a kick back for finding the issue. So, they are or at least should be on the lookout for other issues.
As far as repair option I would go back and speak with the manager. Tell them you want this issue fixed and you want the Nissan part installed. I am sure they will work with you.
In my opinion it is best to stay away from those places and find a good local mechanic. These are usually young guys that need to be babysat. Yes, everyone needs to start somewhere but that doesn't mean it has to be your vehicle. But even the best techs can make costly mistakes and anyone who says they don't is lying.
I am adding an image of the part and retail price as well as the labor times for you.
I hope this helps. Please let me know if I can help any further.
Thank you,
Brendon
