Honda CRV - oil pump shaken itself apart?

We have a 2007 Honda CR-V, Diesel - it's done 61,000 miles. No major problems while we've had it.
We took it in for a service and MOT at a local garage; they replaced the rear brake pads & drained/replaced the oil & filters.
As soon as we drove it the next day, we were away of a rattling noise, particularly loud when the clutch was engaged.
The noise got louder and louder until eventually it wasn't just when the clutch was engaged, it was when the engine was idling too.
We took it back to the garage. After lots of puzzling, they removed the sump and, underneath, found that one bolt had come completely loose from the oil pump and was sitting in the sump, the others were all loose. They say that this was what was causing the rattling.
The implication here is that it's nothing they've done - yet it would be a huge coincidence for this to just magically occur to the car while it was with them.
So, can anybody help me with some possible answers here? In particular:
1. What might have caused these bolts to become loose in the course of a garage doing a routine servicie on a car.
2. We had another garage replace the front brake calipers two months ago, is that something that could have caused this? Does this task involve removing the sump and/or oil pump? Perhaps they left the bolts loose.
3. Is tightening them up going to fix this, or is there potentially an underlying problem?
Thanks in advance - it's scary not knowing much about cars and I don't want to be taken advantage of here; any knowledge here could bolster our chances of getting the garage to accept liability if necessary.

I don't see any connection and shocked that this oil pump waited to essentially fall off almost - pretty much means that engine is toast.
Didn't you get a low oil pressure warning? Just kept on driving away and listen to that wasn't good no matter why this happened.
Never heard of such a thing either on any and not something I suspect anyone would pull for any reason as it would be too much work just to do that if on purpose?

Yeah, after the rattling got worse and worse we started to get the oil light coming on intermittently. That's pretty much when we pulled over and got recovery to tow us home.
One of the bolts had come out completely, another was broken (they didn't say how)... ...it's a mystery.
Does one have to remove these bolts to replace the brake callipers on a CRV? (see my question (2)) Wondering if they were left loose and have shaken themselves off during the service.

Doubt they sell this exact engine in the US but doesn't matter. I've just no clue why if those were ever right that they didn't have an issue instantly when it was assembled new? Can't think of a good reason short of a diesel is a lot more vibration than most "petrol" engines but would design for that.
OK - Now it's what damage did it do for lack of oil pressure if known as it might have survived - can't know without some more tests on it.
Then it's how the heck could it ever happen and if salvageable not do it again! Of the recent work you did the worst mistake I can think of would be forgetting to put oil in or a leaking oil filter fast right away with changing it and still don't know why that would pick on the oil pump! It easily could wreck the engine but not that way IMO and experience. Not a diesel tech but doesn't really matter - they all need fast oil pressure upon start and continuous while running even more need for a diesel but either wouldn't last a mile if zero oil pressure.
OK - for the couple seconds with an oil change if the person can't pre-fill the oil filter (some you just can't) it takes a quick couple seconds to fill it first then on to engine parts. Oil warning would be on but go right out and quiet down engine right away. If they forget something it would if really ignored upon start seize elsewhere IMO.
What does the shop that has it now have to say about fixing this, why or plan for the fix? If this is somehow common to this exact engine Honda may know about it?
Something just doesn't add up to me on this,

You do not have to remove the oil pan and the oil pump to service the brakes on a single thing that has ever been or ever will be made. Your brakes are out on your wheels. Your engine is in the middle of the engine compartment. There is nothing these people could've or would've done to make this happen. You just have an unlucky coincidence. You have a used car in used condition and sometimes things happen. Don't immediately go trying to blame someone else for completely unrelated work when you don't even know how the thing is put together.
If you had just had them replace the oil pump, you would have a valid point. Changing the brakes, even Judge Judy could call that one out in half a second.
We work hard to keep our customer's vehicles on the road. I have dealt with people just like you before who have something go wrong on their car after completely unrelated work and then try to accuse me of either being incompetent or of sabotage. Would you like somebody telling you that you wrecked their computer's hard drive because you changed the ink cartridge in the printer? What you have proposed is exactly the same amount of ridiculous.
