Just to clarify, we agreed that we would pay for the new part and all extra expenses incurred with it. When the part arived it was broken in two pieces where the "mechanics" tried to take it apart. I have no idea why you would take a thermostat apart. I explained to him that I would not be able to refund him the cost of this part because it is now broken. I gave him the option to pay for the new part, take both thermostats to the mechanic, have one installed and the other fixed, send it back, and receive a refund. He said "it's ok just forget about it." We would have covered the 2.17 he paid to ship it. That was never an issue.

But we can not accept a part that was broken for no reason.
