Mazuma mobile does not deserve not even a single star. They are bloody opportunistic crooks. For my Samsung Galaxy Note 8, they quoted £345 online and sent me verification of this via email. I hand delivered my device which is less than a year old and has been kept in a heavy-duty case from new. Below is the exact message they subsequently sent me by email: Samsung Galaxy Note 8 N950F 64GB classed as Faulty - Defective LCD screen. Imprint burn in display. Mostly visible on white background. New LCD screen required. Obviously, I was livid because I knew they were lying. These guys are arrogant lying thieves and should be avoided like the plague!!! DO NOT USE THEIR SERVICE!!!
