I took my car in for new tires and a new battery. When I got it back, I discovered that neither the odometer nor speedometer were working. I raised this with the shop and they claim that nothing that they did could possibly have impacted the speedometer function.

I find it rather too coincidental that everything worked just fine right before I dropped it off and failed to work at all since I picked it up. Can anyone give me any advice on this? I'm going back to talk to a manager to try to get a result.
