What about a humble letter, uncomplainingly explaining your situation, asking for help. If this is refused (unlikely if I were to write such a letter) you might see if the professional association would be help. Either way you'll have to be nice.<p>PS sometimes you can strike a case where the person who is supposed to do the work gets a huff going or something and will not help whatever. Sometimes you can ask a lawyer (? your country) to make the request on your behalf, which is likely to evoke a response.
