try using Dua Hari Lambat in Penang. You will cry.
Item(s) arrived in the morning. But they need your permission to clear. Must fax over the instruction slip. Then later once you asked them to proceed, they claimed customs want to inspect. Even the internal worker ask me for 'coffee' money to expedite and ahem customs.
Bear in mind i got regular shipments bi-weekly still need to do the above. Arrival in Penang does not guarantee same day delivery. Even i must go Customs and explain to them the items about, the DHL runner just sit and side with customs and tell me must not cheat Customs..WTF, who is paying you the salary?
Also charge you RM20 or something just to pay Customs duty and tax in advance for you.
Changed to FedEx 1 year ago. All on time delivery if flight arrived in the morning. No 'coffee' money needed and duty and tax FOC upfront payment. If consider FedEx charge more, then it is worth every penny.
Now Dua Hari Lambat kept on sending emails give special rates for shipment, their volume must be pretty bad or most people abandoned them.
Also i knew all the Customs and procedures as I am in the same industry as them. No need to BS me.
