2003 Pontiac Grand Prix 6 cyl

I brought my car to the mechanic to replace the relay, replace the wiring, and recharge A/C System. After they did this there has been problems with the speedometer. Can I hold them responsible for this?

The speedometer will say Im going 40mph then move around and hit 0. Sometimes itll work then just keep moving around.
