Avoid like the plague, con artists. Offered me £431 for my iPhone XS Max. When they received it, they said it was only worth £340 due to damage to the phone. My phone is immaculate, I have photos to prove it. I told them where they could put their offer, politely. A few days later, after some discussions with a manager (yawn), I was offered a much improved £367. Again, told them no, less politely, and to give me my phone back. Eventually got my phone back, after 2 weeks of tossing about. No silicone case I sent it in, no iPhone box I sent it in, no apology, 2 weeks wasted, never trust these clowns.
