i brought a £950 laptop off of them, in a year and a half it has gone wrong 3 times and had to be taken into repair. the first couple of times apple fixed it no problem, the 3rd time apple sent me to john lewis to get it repaired under guarantee as the part needed would cost around £400. when it went into john lewis, they rang me up 2 weeks later saying £400 must be paid as it was liquid damage, however this had never been mentioned by apple. the customer service was nothing but horrendous with constantly rude staff. after ringing up and emailing we decided to get the unrepaired laptop back to the store as john lewis were very unhelpful and so we decided to go elsewhere. when we got the laptop home, we tried to turn it on on the off chance it would work, and so it did, perfectly. therefore john lewis tried to get me, an 18 year old to pay £400 for basically no reason, i am so glad i didn't pay it and will never be going back to john lewis again!!
