I don’t know enough about your return to know whether it was you or they that were difficult. You’ve given zero details or context. It sounds very unusual to need 15 emails. There’s a complaint escalation tab in your online account and you can create a “case” if you are dissatisfied and want compensation.
I buy all my white goods from there and as much as possible of the rest. I have a John Lewis credit card and get vouchers to spend and perks connected to it.
I’ve had some issues over the years due to the sheer quantity of purchases - from mattresses to cutlery to light bulbs to kitchens/bathrooms. They’ve always ended up rectifying to my satisfaction and if they’ve really messed up they give goodwill compensation - something you will not get elsewhere.
I had a light that was faulty after 3 years - where else gives a 5 year warranty on lights? They paid for my electrician to take it down and gave me a swift refund.
My Bosch dishwasher is currently faulty. I called them on Monday and an engineer is coming tomorrow. When they fitted it last year the fitters fixed one of my cabinet doors for me at the same time 😮
They give double the warranty on electricals as standard. That is worth a lot of money! If I buy an iPad for almost a grand I think it’s awful Apple only provide a warranty for a year - but John Lewis will give me 2.
I have a John Lewis branded washing machine and fridge - they’re made by Electrolux and I have no complaints. They came with 3 year free warranties - again no one else stands behind their products like this.
A few years back I bought a bread machine for Xmas for my parents. They delivered it in branded wrapping and ruined the surprise. I complained and got £50 goodwill compensation. You do not get service like this anywhere else.
I also like that they’re a Co Operative. One of the largest in the UK.
So, for a host of reasons, I will continue to shop there 😀
