Appalling service. Bought refurbished phone. Faulty. Repaired twice still faulty. Cancelled order and new phone sent. After a few months Faulty. Two and a half weeks in repair. Replaced 16gb with an 8gb and still faulty. Absolutely worst company I've ever dealt with. Complained to trading standards and from the look of their twitter feed I'm not alone.
