Apple South Africa (Core)

Worst experience of my life when it comes to customer service I bought a brand new iPhone turns out there was a problem with dust under the camera lens and it was showing up in pictures they sent it to Core and fixed the problem I received the phone back 3 days later with a new number of problems mainly the home button not fully functional I took the phone back sent it back in had to fight for a week to receive a new phone. Now the new phone has the same manufacturer defect and Core is doing nothing about it i am furious DONT BUY APPLE FROM THE ISTORE!!!.
