John Lewis ipad Free extended warranty - Not what you think!

I purchased an ipad mini from John Lewis because they claim to offer 2 year warranty - one year being manufacturer's and one year extended from John Lewis. If you think this warranty will be the same as Apple's then you are totally wrong. And I am one of those people.
My ipad started to develop some issues eg freezing, suddenly becoming very slow etc. I took it to the John lewis in Southsea only to be patronised by the 'tech expert' instore. I listened for around 10 minutes how he tells me what I am doing wrong despite me already telling him that I have tried the reset and restore option. I realised this was a waste of my time and politely said goodbye and left. I then proceeded to book an appointment with the Genius bar in Southampton when my ipad was tested and a report was produced listing the issues and a replacement was the solution. I took the report to John Lewis Southampton - and I was told by another 'tech expert' that despite the Apple report, they had to send my ipad away and that I might get it back within 28 days....... When has John Lewis engineers been more knowledgeable than Apple Genius bar staff on Apple products?
Anyone out there currently tempted to buy an ipad from John Lewis because of their free warranty offer, then think twice and it might not be worth your time and effort! I wish I had bought the extra warranty from Apple directly and the money I have spent in petrol and time wasted would have been saved - not to mention the stress and frustration!
I shall update this review once I hear back from John Lewis!
