I sent my phone to sell which was quarantined because it was on contract with EE. Followed the process provided by Mazuma team and got it all cleared from Checkmend and third parties. Paid the £10 admin fee for them to return the phone via special delivery which took 6 working days, (it took me 24hrs to send via post office special delivery at a cost of £7.50). However, when the phone in its original box arrived I noticed they had peeled off the label on the back of the box which states the Imei, serial number etc. Strange activity, and all I need to know is why? And they never once ask if the phone is in contract, except if it’s locked or unlocked and on what network. It’s in the small T&Cs which a lot of people will miss like myself and I take full responsibility of my ignorance. Then they charge £10 admin fee to release the phone. Haha exploiting the vulnerabilities of customers via marketing the easy sell/buy process. These flaws can be removed from their business model but then again charging £10 admin fee is good for the business. Ethical? LOL
