Community GMC, Inc.

I will preface this by saying my father was a mechanic and ran a very successful shop for more than 20 years. He was honest and he was good. I understand labor is part of the cost of repair. However…
My car battery kept dying. Community GMC couldn’t figure out what was draining the battery. We told them it may be the radio, as it had been malfunctioning. They ignored us. After hours and hours of trial and error (and charges), they found it was INDEED the radio and disconnected it. That was the «big fix.» If I wanted the radio replaced it would have been another $ 500.
Should I pay for their incompetence? I think $ 300 for labor to diagnose a problem is too much.
I paid $ 300 for Community GMC’s incompetence. Battery draining is common in the model of car I drive. But, these so-​called «experts» didn’t know?
