Emirates airlines Broken business class seat

Whilst recently flying from heathrow to dubai with my family on flight ekoo4 on the 7th of April 2013, passenger name hill seat 18e my seat would not operate and had to be reset at least 3 times. This was a night flight and because of this fault I was unable to sleep. I hope you appreciate that this is unacceptable and would like to know what your policy is for refunds etc.

Thanks
