Ah... The deliights of working for a Nigerian Company. You must realise some Nigerian Companies are not accountable for paying expats so you have made the right decision.
I suppose now that you have left, they will never pay you what you are owed and will be re-cruiting the next batch of pilots from somewhere else in the world.
As for maintenance and spares, don't let that worry you, they won't be doing any of that either!!
