After 18 months my iPhone X went on the blink, and when diagnosed at Apple, they said the processor was putting the machine into Panic mode and it wasn't worth repairing the phone. They offered an instant replacement ( for a fee ) as it was out of warranty. As it was under John Lewis 2 year guarantee, i took it to the local Kingston store. I was quoted 10-15 days to repair, which is scandalous since I had the diagnostic report from Apple. 28 days later I still do not have my phone. Imagine going a month without your phone. Because I had replaced the screen with iSmash, I had to pay John Lewis 279 pounds to bring it back under warranty ( the screen was never replaced, as they will be sending out a replacement unit, so feel pretty aggrieved) But the fact that JL send it to a repairer who sends it to Apple is in the modern tech age frankly quite antiquated. If they lose the trust of the brand, then in the modern shopping environment, they will surely suffer exponentially. Far easier to buy direct from Apple and purchase Apple Care and then the phone would have been with me on the same day. 28 days and counting - ridiculous - be forewarned
