Glad all is working OK but to be honest you may find it doesn't work for long
The master cylinder is linked directly to the slave and if the slave is the problem then a new master will not sort it. The slave is inside the bell housing and usually it makes sense to change the clutch at the same time as sorting a new slave cylinder.
The garage will/should know this and I'm surprised that they didn't discuss it with you.
I hope that things stay OK but if not let us know so you can be 'armed' when you go back to the garage
