Just to share personal experience of DPD.

A friend of mine sent an item from the UK to Malaysia using DPD. I couldn't find who's their agent in Malaysia. But I ended up calling this courier company Consol Express Service Sdn Bhd - https://www.facebook.com/Consol-Express-Ser...04525718048353/

Their phone number during this writing is 03-7880 7552. Apparently, they are the agent for DPD in Malaysia.

They have passed my item to ABX Express with a new tracking number. So using that new tracking number I was able to track it on the ABX website.
