This service is diabolical. They give you a delivery time of all day 8am-6pm. I stated that I needed my item delivering before 5pm because my factory would be closed. Of course, DX apparently turn up after 5pm and cannot deliver. I then re-book the delivery and state before 3:30pm in the special instruction box. Again, this is totally ignored and I do not receive my parcel. I paid £5 for postage and have been waiting for my items for over a week now. The customer service line is terrible too, they contacted the driver for the order and couldn't even give an estimation on time that they may have been arriving.
Totally unacceptable, shocking delivery service, and make Hermes look like Special Delivery Royal Mail.
