Ordered a phone on 4th Dec, advertised as arriving in 3-5 working days, nothing. Queried via email as could not get through on phone or live chat, they said delay due to quality control, but that it would be with me in another few days - 18 Dec still nothing. Given the other review stating this I am now thinking this is dishonest. Am going ask for a refund now as don't trust this phone will get to me and was a present for son's birthday - now missed. Terrible service. They should be contacting customers to explain delays. Would give zero stars too if that's an option.
