What post office is assigned to Brgy. Bahay Toro, Quezon City?

I ordered a book online (not my first time) and I still don't have the book. It's way past its estimated time of arrival and I'm starting to worry. I would like to check the local post office to see whether my book has arrived. I was hoping that it would arrive faster if I use my Manila address than my previous Bulacan address, but it's proving me wrong. Now I'm asking if there's a Philpost branch assigned to our area (zipcode 1106) or should I go to the Quezon City central post office.
