Collecting a parcel from Overseas

I received a form through the mail telling me that I have a package arrived from overseas.

I can read from the form that I have customs duty to pay and that I need to bring ID to collect the package.

There is NO address, nor telephone number on the form and all that I can establish from Cambodian local people is that I have to go to the "Main Post Office" near the river.

Can anyone help with an adress? Telephone number? Opening hours?

Any help would be gratefully received as the package contains important medical supplies.

Thanks in advance.

Thanks for the help.
I went to the Postb Office on Saturday morning but was unable to collect the parcel as the department that takes the customs duty only works Monay to Friday.

regretfully i wish you all
