Frustrating, I got an Iphone 7 on an optus plan only for it to be faulty. The dramas between optus and apple. I was told it would be quicker to go to Apple but honestly I don't think so. I was on hold for 10 minutes only to be told I need to be put on hold to make an appointment . Another 15 minutes and I am still on hold. Ridiculous
