I have to say, that is the best 1 iv heard yet!!.. your clutch went and we had to replace your gearbox!!. NOT POSSIBLE!!.. as a bell housing seperates the clutch from the mechaics of the gearbox. Most parts are available to purchase for your gearbox anyway so they wouldnt have had to replace your whole box.. Ask for your old gearbox, my guess is they didnt change it atall and will be unable to give you your old box because its still in the car, If they do give it to you, take the gearbox and get it checked.. would have been alot cheaper to have your old box reconditioned than to buy a new one anyway.. good luck,
