Dodgy delivery service!!! You DX is in cooperation with Her Majesty Passport Office, you carry VERY IMPORTANT documents. However dodgy DX delivery guy did not come to my property, even did not call me, did not ring the door bell etc... Because i believe that he/she just marked as "Attempted" on the hand computer without visiting my address!!! I just spoke to customer services after i received the dodgy, lie "attempted" notification text, spoke to Michael. He tried to help me and called that dodgy delivery guy many times as well as DX Heathrow depot whilst i was waiting on hold but unfortunately delivery guy did not pick up the phone as same as DX Heathrow depot! If you can't deliver the very important documents on time then why do you work with the HMPO???The HMPO should stop their agreement with DX immediately. Don't trust DX and its liar, dodgy delivery guys!!!!
