Please be advised that I do not practice law in Georgia. I have an inactive license in georgia. I am attorney in Florida.
What agreement did you enter into whether it be written or oral for the the repair or to determine what was wrong? If there was no agreement as to what you would pay them, under Florida law they would have to sue you for quantum meruit, meaning they could sue you for the value of their services. Since they did not provide any value to you you do not owe them for the work.
Whether you have a cause of action against them for tearing up your bath is more difficult since you do not know what was causing the problem which they were to fix. If you have an expert who would testify that the problem was was easily determine and what they did was unnecessary I do not know that you would have a cause of action for your down stairs bath.
You should consult a Georgia attorney,
