I don't know what exactly they do on a CLA but I believe a partial disassembly is done and I would at least expect them to check that all shutter/aperture settings fire ok. Not necessarily time the shutter speeds but at least make sure the rings all go to the correct position and "something" happens when they then fire the lens, so any issues (if you didn't mention them) should be readily apparent and during final testing they should spot this rather important problem.
Ask what they did (if anything!), why they didn't fix the issue, why they didn't see the issue still existed after they "serviced" it and basically ask for your money back and send it to Hasselblad or some other repairer who has a better reputation.
