They should just fix it for you.

They would have had to pull the gearbox out to do the job and if the clutch wasn't aligned properly the gbox input shaft wouldn't have gone back in easily. They did the job, they should fix it. More likely to be a detent issue.

Just don't go in there with a full head of steam, workshops hate when know-it-all customers come in and demand shit. It could be a few different things.
