Unacceptable!!!!

I am extremely disappointed with the support I have received from Sony but most of the the Sony Experia Z3!!! I have been a loyal customer of Sony's for a long time with TV, Gaming Consoles and more and that ends today!!! My LCD Screen started paying up during the night on my Sony Z3, my phone is only 4 Months old and has never been dropped but I still get quoted R2100 to fix a malfunction. I expect something to be done about this!!! My phone has not one single scratch on it and am extremely disappointed in the brand. I used to Rave about you products but if something is not done about this I will make sure I will never support you again and I will make sure my family and friends don't either
