******* QUALITY * FREEZING IPHONE6

I had my Vodacom contract iphone6 for 3 weeks before it started freezing. Gradually it got worse to the point where it would not respond for a day at a time!!! Eventually got sick of battling and took the phone to an istore where they did a software update and told me if it still freezes to take it back to Vodacom. Needless to say it froze not even 2 hours after the update. I took it to Vodacom & told them it had a software update, they sent it in, it came back with JUST a software update because Apple did not note the update on system. It still froze!!! Took it back to Vodacom & it took the useless store a week to send it to a repair centre. I am disgusted with the quality and will tell everyone I know even on social media to STAY AWAY from Apple products they are *******!!! Furthermore Vodacom and Apple must dream that I will pay for the repairs!!!
