DO NOT USE DPD!
DPD are hands down, the most unreliable delivery company in the UK.

I have lost two days work waiting for deliveries that never arrived.

On their online parcel-tracker, it claims I 'refused' the delivery and therefore the package has been returned to the sender. This is obviously complete nonsense.

I have read similar reports all over the internet and find it baffling that so many retailers still use this terrible company for their deliveries.

Avoid at all costs.
