SAMSUNG FRIDGE NOISE

I recently purchased a Samsung fridge from Hirschs which is making an unbearable high pitched ringing noise - so much so that I wake up in the morning with ringing in my ears - according the Samsung repair agent this is " normal " for an inverter fridge [ Samsung do not even employ their own technicians but use sub-contractors who decide your fate if you have a complaint ] I refuse to accept that this can be normal and the noise is causing me significant distress . Samsung please live up to your name and assist to resolve this .
