my car is overhearing what should I do?

What is your question?

had a crack in my radiator that I patched with epoxy which fixed it.... until my carwas towed down a hill... which I thought may have cracked my radiator again... but when speaking to towing company after he put water in my radiator which still ran hot he then insisted that it was my water pump.... reserve tank is completely dry after filling it up and driving a short distance don't know if he is trying to get out of fixing something they broke it is it really my water pump
