That freight RM535.54 must be from forwarding agent in P.Pinang dealing with Pulau Pinang's customs.

Seriously only in Pulau Pinang so far I know they have this kind of thing. Usually target DHL forwarding services. Even if your item stated clearly on the invoice the shipping cost with signature, they will suka-suka put RM535.54 as if no shipping cost written in the invoice.

Thats why I ban DHL and Fedex for a long time now, and ask the international seller to ship to me using courier that link to Pos Malaysia.
Customs that work in Pos Malaysia Office will use the shipping cost on the inovice to calculate the CIF ( cost + insurance + freight ) and not put RM535.54 suka suka hati like the Pulau Pinang forwarding agent and customs.

And I tried to find this RM535.54 in Federal Gazette related to customs taxes, but I can't find it. Public should be aware of this.

This kind of practise really shady and I still keep the evidence until now.

My item RM254.48, including shipping.
They charge freight Rm535.54
Insuran : rm2.54
Total: rm792.56

Kena tax : 79.26

I live in Selangor but encountered the same problem thrice. I still keep the papers from Customs and submitted a complaint (with documents and everything) but the status remains as 'under investigation' since September.

Likewise, I'm also staying away from private shipping companies.
