wouldn't that depend on who you signed the contract with, the practice or the doc himself and what it says in the contract?
i'd think you can win this, you went to the practice because of that doc. the new doc should just refund you, that's the right thing to do but if he wanted to push it - i think you have a chance.
but that's only if the contract doesn't have a situation like that written out.
interesting case, maybe someone here knows the law, i'm interested what they say
ETA yeah, i feel your pain too)))) i'd be annoyed myself, that's wrong no matter what the law says
