Horrific experience when trying to sell my device to Musicmagpie. Sent a basically new device after a warranty claim to them for assessment. Cost £10 for special delivery. I was told that my device wasn't as described due to being 'knox void'. I was offered 10% of the original quote. They returned the device and I confirmed that Knox wasn't void and the protective plastics included by Samsung were removed and there was also a slight mark on the inner screen. I reached out to their customer support and provided photo evidence that my device WASN'T Knox Void. I was just told they won't refund or offer to pickup my device again and won't reassess as the review was completed by their 'expert technician'. Also they wouldn't help around the damage without 'timestamped' images showing before and after which I didn't have (granted my own fault for trusting a company to be careful with my device). I will never use this service again andwill avoid at all costs.
