Ordered iPhone 6 for my son on December 4th, they took the money straight away, they said allow 5-7 working days for delivery, the phone never arrived, contacted them numerous times, they sent the same e-mail, about order being delayed, the fact is they never had a phone to sell. Cancelled order, when I knew I wasn t getting it before Christmas. Eventually got my refund today. Also there phone is constantly off the hook, do I need to say anymore, very stressful experience.
