I have ordered some thing and the supplier uses XDP for the courier service, I used my work place as the delivery address as some one is in all day, they have 3 times now delivered out side of office hours despite the supplier I bought from requesting office hours delivery, every time they attempt to deliver they send an email asking me to ring a number to arrange delivery, I must have rung this number 50 times over 3 days at various times of the day and no one answers, How do they expect to sort issues like this if they do not answer the phone, this is the worst courier service I have ever experienced
