How to contact PhilPost Delivery?

Hi! It's my second time having something shipped something from the US to the Philippines and saw na yung PhilPost yung local carrier. Nakatag yung package ko as "Your order is available for pickup" sa website ng US courier then sa PHL Post naman "Receive item at delivery office".

I tried calling the hotline pero laging busy, 'di ko sure f they're going to deliver my package :'') Huhu can someone shed some light on this or tell me alternative ways to contact them?
