We do want our customers to be happy and we have taken care to ensure our phones are as described and fully functioning. However, sometimes things break and sometimes customers are “disappointed” with their purchase. Our guarantee is there for just these occasions. All of our mobile phones (except those marked “As is” or “faulty/spares”) come with a 14 day guarantee against defect. If you have any problems with the phone in the first 14 days, please contact us and we will do our best to help you, which may include providing a replacement or a refund.
