Was in the Apple Store on Regent Street buying a new phone when I inquired about a trade in with Apple directly. The gentleman serving us told me that the handset (iPhone 6S) was "in mint condition" but was only able to offer me GBP40.00 I quickly sent a request to Mazuma which came back with GBP65.00 so I politely declined Apple's slightly less, but more genuine quote and decided I would use Mazuma. Long story short, I received an email shortly after sending them my handset that the offer was no longer GBP65.00 and would now be GBP25.00 as the handset's unlocked status was "poor" (whatever that means) and that the camera had a crack! Absolute joke, the phone I repeat was in mint condition and was in a case from the moment the phone was first unpacked. I called and someone by the name of Benjamin did say that these instances do occur so he manually rejected the GBP25.00 offer so that my phone would be returned to me and said that they would seek damages against Royal Mail. I followed up a week later only to be told by Victoria that they are unable to raise a claim with Royal Mail as the packaging upon arrival was not damaged. There is no resolution or offer to help, just a very insult to injury-esque "sorry" but nothing else can be done. Honestly, it's quite clear from all these other reviews that these guys knowingly offer more attractive prices so as they ultimately end up being chosen for the trade-in but then use untrue and ghastly excuses to undercut someone, who's handset they are in the possession of. It does make me wonder if perhaps damage is caused intentionally? We should all raise a legal case and investigate whether there have been any whistle blower cases recorded as these con artists should not be allowed to continue doing business. As per everyone else here, wish I had read these reviews first!
