Sad to see Mazuma have join the ranks of rip off Britain I sent a Samsung s6 and s6 both in perfect working order kept in cases no scratches, next day delivery. Next morning 8.15am received email saying 'we have your mobiles' 20 mins later another email saying S6 has imprint burn in display mostly visible on white screen. Quick work to find a bad fault........... that reduces their offer from £99 to £27.50 (argos vouchers) The S5 was fine, £49 was offered, so the total offer was cut in half to £77.00. from the original £148.50. Quite obviously they work quickly so you just except the SCAM, especially on more expensive orders. I rejected the offer and got them to return the S6. The phone was perfect for 2 years old, its quite clearly a scam they can level at any Mobile of any age. Don't be fooled or scammed by these cowboys, just get them to return your phone free of charge, and hopefully they will soon get what companies like this deserve.
