Another update, got a call from the executive who took over the case while the original executive is on leave. He said the case is still in progress but they don't yet have all of the info required to make a decision on the consumer law claim... he said they have around 60% of the required information and the delay is due to consumer law claims having 'a lot of moving parts' (whatever that means). He did, however, tell me that if they believe I have a claim, I will need to have an authorised service provider assess the device for damage (understandable) and that I will also need to provide the original invoice, despite buying direct from Apple, which I did after the call.
He said it will take 1-3 working days for him to get the remaining required information which he has requested internally (again, no idea what information they're talking about), and then he will be able to come back to me with another update on the case. So... possibly progressing? Quite confusing, though.
If you don't mind me asking, did you have this much strange back and forth and waiting while they continue to 'gather information' and 'investigate' in your case, before they agreed to replace it for you?
I've spoken a lot about the problems with the device, how they've been causing me issues and are not of satisfactory quality for an expensive device, and also how I have been a loyal Apple customer and have purchased many Apple devices, and this is the first and only one thus far that I haven't been happy with, so I would appreciate if they grant a replacement under consumer law to rectify my poor experience with the device. I've never had any dealings with Apple support for any other Apple product prior to this one. I'm surprised the executive care agents are going through the motions with me on this, as I would have thought it was going to be fairly straightforward, reading other people's experiences with this department with similar hardware issues.
