Extremely unsatisfied

Worst service ever. I will never buy a Hisence product again. My fridge broke under warrantee and the first technition came out but did not fix it properly, so I had to call Hisense again to complain and they sent out a second technition. Spares were ordered without any feedback from Hisense or the technition. Weeks later my fridge is still not cooling to temperature and I can't turn on my ice maker as the water is just running through the ice maker to my floor. If I call Hisense head office the guy there don't even let me finish my sentence and I can't even complain at head office.
