Isn't there any way the government of the Philippines can improve their mail service?

Yes it could be improved but that would entail getting rid of a big bunch of thieves that got their job thru political connections.

I certainly would like to see them go also however I doubt it will ever happen.

Like I said the only way to fix it now is thru mass firing of the people in Philpost.

I feel you. I only received a few mails (containing important documents) using the Post Office. Some never arrived. I agree with @frostitute, use a private carrier instead like LBC.

No because he collect, 1 % percent gain if there's something to be collected, then the director of the post office is 1% too. why they should intervene when money is officially collected and they've got the white card of admission to the business.

USE A PRIVATE CARRIER INSTEAD.
