Horrible experience so far, and still haven't even received the actual product (refurbished iPhone 7)...... Ordered 28th December to ship UK - Ireland. Should take 5 working days, right? It's the 23rd today, still no product, had to remind them to ship it about 12 working days after order since didn't get tracking ID or any news... They have a great online image, but so far my experience is horrible, have a bad feeling about the phone as well now wouldn't be surprised if it came faulty...
