sent a faulty iPhone 5s 32gb Gold (bought refurbished from musicMagpie via amazon in 2015) but I put it in an older iPhone box (for a broken iPhone 5s 16gb Silver which I had sold to Mazuma). They do say any box will suffice but don't believe them! I am pretty certain that they used the IMEI on the box to do a checkmend report instead of the iPhone that was sent, which showed a block. I asked them to run the IMEI report again using the iPhone I sent and not the box. They came up with another report (not apologising for previous mistake or explaining anything) and sent a report id no and saying that there is still a block that I need to have removed. When I checked the new report no, there is no red flag mentioned on the report at all but weirdly the report is also dated for May 2015 when we are in May 2017. When I queried this, I was sent another auto email repeating their previous email. Checkmend are themselves rubbish communicators - the people receiving the emails (i assume people are replying but not sure) is also sloppy, robotic and irrelevant to the query. For £25, the irritation this is causing doesn't seem wroth it. They say they will recycle responsibly if the issues are not resolved. I hope that this is at least what happens and they are not just going to be rubbish in doing that at least. I had a flawless experience with Mazuma and would recommend them heartily - they will also send you the packaging. I most certainly DO NOT recommend musicMagpie. Suspiciously, musicMagpie appears to query negative reviewes on trustpilot where I just published this review. Trustpilot are actually taking them down and asking customers to send evidence to back up experience. I have done this but anyway - do beware!
