Where did you take it?
Might be worth just telling them to forget it and picking it up. It's not a big job, it's three door cars off, 2 bolts for the window, 10 bolts for the inner door bit and two bolts for the door lock module. It took me about 3 hours to figure out how to do it myself for the first time. I could now do it in about 45 - 60 mins.
Ring up ask how much work they have done on it. If they say lots, tell them they are bullsh!tting. If they say none, say take the car away and do it yourself. Or ask for a definite date and price for it to be finished.
DIY is very easy.
EDIT: To be fair on the garage, if they had you booked in the week before and are at capacity this week. You got the parts to them by COB friday. They've only had the stuff to do the job less than three days. As much as it's annoying when it's your car out of action, you cant magic 11 hours work from an 8 hour day.
