Sent them 2 iPhones, iPhone 7 quoted £100 and iPhone 8 £140!! Got e-mail saying they had both been downgraded due to screen issues or white bits? They offered £50 per phone!! Called up and queried this and was told that the pixels go over time and cause white bits not visible normally. I questioned their over time theory as one is a year old!! They couldn’t answer! I e-mailed and asked for pics of my phones showing this and I got send some pics of a white screen with something circled that looked like camera flash reflection from photo being took!! Beyond livid!! After speaking to husband we were to worried to ask for phones back incase they came back faulty so we felt stuck!! We ended up feeling like we had to accept! It killed me as we work hard for our things and these phones were being sold to be able to get my teenage kids upgrade for Xmas which now we are down on cost. I know there was not a thing wrong with them!! They were well looked after, had cases and screen protectors on and not a mark on them. Feel totally conned and will not be using mazuma again! They are total scammers!! They quote for it and then downgrade and they classed the phones as faulty!! How on earth are they faulty??!!!! Scammers avoid at all cost, would if gave 0 stars if I could!
