Water pump

Took my car to john as water pump and thermostat went out, (these are parts that are driven by the timing belt) John just replaced the water pump and thermostat, failed to change the timing belts as (he should of known being a mechanic that any timing belt driven part when goes out you MUST replace the timing belt too with fresh new one) several days later, timing belt snapped, cause all major probs, took it to another mechanic for second opinion, to find out i need a new engine, at $3640 later, due to johns negligence tried to go back to him and tell him, he acted like he didn't understand me with his foreign accent, acted like we had a communication breakdown, also my mechanic who replaced the engine noticed that several parts that john supposedly replaced were used parts, john charged me for new parts yet later discovered they were actually used dirty parts. John charged me for new one and I got a used one. My type of car you can't just buy a Waterpump on its own it comes with the full timing belt kit as a package. This is the reason why my belts weren't changed and caused to break on me and caused serious damage to my Engine due to johns negligence by being cheap and charging me for new parts. This guy breaches the "Lemon Law" Be Careful!
