To start with the customer service was brilliant, I bought a refurbished iphone with a brand new battery and it was great. 6 months in and it got hot when charging so I sent it back to be fixed-after having to declare I hadn't dropped it or immersed it in water or allowed it to get wet-none of which was relevant. Two days after they received it I got a report and photos 'proving' it had got wet. The report stated as such and I discovered that the 'new' battery which I had paid extra for had been manufactured in January 2020!! it was already three years old before it was put in my phone. Long and protracted messages assuring me of their continued care,-rubbih- but they cited the selling company-BOOST GADGETS had declared they wouldn't repair it under warranty because I had got it wet! RUBBISH! I finally received it back 4 WEEKS later! It works, but I will NEVER buy a phone-or anything-from them again-they pushed a discount to buy another phone, or a discount on REPAIR!! which I declined. It may be BOOST Gadgets rather than Backmarket, but they did not stand their ground re the warranty. VERY DISAPPOINTED!!
