Driver used foul language when I asked why the package was 4days late and said that the package was on time, when he started getting aggressive I began to film him. As well as customer service laughed at my wife when she said that the item that needed delivery was food for our dogs and that they are on a diet that can't be altered or they get ill. The complaint advisor said that the food could not be delivered when they had promised because it was too large. The food is 3kgs and the size of a shoe box. We complained about DPDs awful service and employees that where not completing tasks that they promised to do and they said sorry and then considered the complaint dealt with.
