Dunn's Auto Stop

ok so i got a new crankshaft sensor put in the other day only to have my car break down on my way home! i had to push it 4 blocks home. Then when i call they guy for a tow he tells me its gonna be 30 bucks haha yeah rite. So i call East End auto and they get her running like a champ. they ended up taking out the sensor dunns put in. when i tried to return the brand new sensor Mr. Dunn would not refund me. Never go to dunn's unless you enjoy the feeling of being completely ripped off and then being treated like an idiot for questioning thier (horrible) work. Never ever again.
