Pushed from call center to call center

I have had 2 sony Xperia's. one Xperia Z and one Xperia Z2. on both of them the screen shattered after only 1 month. the first I had repaired. the second however wasn't not able to be repaired and Vodacom said sony should replace it, however sony said, there were no Z2's in the country to replace it with so tough luch. I have been fighting with sony customer care sa and sony customer care international for 4 months now. I have been pushed from pillar to post, back and forth between customer care and have had no luck with Sony. I have had to subsequently change to SAMSUNG. Sonys customer service is disgusting. i was a loyal customer, but from now on will only buy samsung. R30,000 down the drain. Thank you SONY for being such a rip-off and having no regard for your customers
