Do Carphone Warehouse get repair deliveries on Saturdays?

When i was at the beach a few weeks ago my friend was using my iPhone 3GS and my other friend was throwing pebbles at my friends shoebox. My friend thought a good idea would be to stick my phone in front of the pebbles and smash the screen. I sent it off for repair, but it's taking ages, and i was wondering if they get the phones delivered to the STORE from the repair place on saturdays. It was sent last thursday or friday, i forget which, and it's still not here. -.-
