Refund on bad repairs

I took my car to a repair shop at least 4 separate times due to overheating. I did some research, consulted an outside mechanic and told the shop I believed it was the radiator. Every time I they said it was fixed, it was not, resulting in me being stranded on the interstate 3 times, and eventually a blown head gasket. The shop had replaced the thermostat (twice), 3 hoses, and a temperature sensor. I took it to a new shop that found a baseball-sized hole in the radiator and the blown engine.
Was the first shop negligent to the point that I deserve a refund, or even a civil suit?
