Review Unprofessional worker

I went to Iligan post office to claim my parcel since I was texted that my parcel was already there, and I'm a bit confused because when I tracked my parcel, it just departed in metro manila. But I still went there since it only had a 7days pendency. So I was there at 10am monday. And for almost 1 hour they spend the time finding my parcel. So I told them that I'll be back. When I came back, they are just sitting there. Then this UNPROFESSIONAL worker in ILIGAN POST OFFICE
She didn't help to find my parcel. I gave my tracking number to her. Then, she somehow scolded me because my parcel was not yet arrived in Iligan and I told here about the text, then I'm expecting her to say sorry for the mistake they've done. But hey people, she shouted me saying, "YES THERE'S A TEXT BUT, YOUR PARCEL IS NOT HERE. YOU SHOULD COME AFTER A MONTH OR 2 BECAUSE YOUR PARCEL JUST DEPARTED"
And that triggered me, I just want to hear an apology from her since it's there mistake, and I don't know how things works in post office. Mukha pang ako yung may kasalanan.
