Had you signed a teaching contract with that school before you embarked on your runner? If so, you've been dishonest, and are therefore not entitled to any sympathy re what's happened to you since.
Contracts should be obeyed by both parties. By doing a runner, you've broken your contract. Not what I would have done if I had been in your shoes. And now you must bear the consequences. What's there to complain about? As far as I can see, nothing.
