Are they including a new engine with this Cat? If not, they are
thieves. Certainly 'not' trustworthy enough to give you a straight code
answer.
A loose gas cap even will cause the check engine light to come on
intermittently.
Can you not get your own codes on that one? I don't know, but if you
can, you turn the key to get them. You go to run, off, run, off and run
again and watch the dash for either a blinking light you count the
flashes or a series of numbers starting with a P will flash.
Some auto parts stores will also check the codes for free.
If you can get that, then let us know the codes.
You can also clear the codes by unhooking the battery for a few minutes
so if the light doesn't immediately come back on, you shouldn't get
suckered for emissions.

I was getting a random check engine light a couple months ago.
Disconnect my battery to re-set the codes and it would come back on
once in a while.
Was starting to do the research to correct this then I happened to
check my oil and the dipstick was not down tight in the tube.
The light has not come back. Coincidence?
On my YJ I swapped in a new cat for around 200 bucks

"One of the three" catalytic converters? There is only one. They want to
sell you a "rebuilt" unit? Run, do not walk, from this place. I would guess
you have an O2 sensor about to go, probably time to change all of them.
Often an intermittent CEL will indicate a minor emissions fault, which isn't
critical to engine operation. A failed cat means you will hear the element
rattle inside the housing.
Anyway, find someone else to check this out.
