AITAH for not picking up my food order?

So this afternoon I called a restaurant to place an order for noodles and a rice platter. It was 3 items which they quoted me for around $50 and they said it would be ready after 20 minutes. I arrive there 20 minutes later and go to the pick up window. It’s closed. So I go to the front door to see if maybe they have it waiting inside the restaurant. The entrance door doesn’t open. I go back to the pick up window to see if perhaps I missed something but again nothing. So I thought maybe I didn’t tug on the door hard enough cause I’ve done that before. I try again and sure enough it’s locked. So I peek in one of the windows by the dining area and there’s no customer or staff in sight. The open sign above it is even off. So I go back to my car and wait another 5 minutes to see if someone will pull up. I look up their hours and it says they’re open and confirm I’m at the right address. I honestly don’t know why I didn’t call again but at that point no one has shown up and the parking lot remains empty so I decide to drive to another restaurant and place the same order. I’m driving back with the food 15 minutes later when they call. My daughter was playing on my phone in the back seat when they did so the call was screened. They called again 10 minutes after that one and left a voicemail. At that point I’ve already made it home and was eating with my parents. I check the voicemail and it was one of the male staff saying “you motherf*ckin b*tch you don’t come for your order so f*ck you”. They have since been blowing up phone. I literally have 71 missed calls from them with the last one at 9:38 PM followed by another voicemail of repetitive “f*ck you f*ck you f*ck you”. I know I could’ve cleared it up by calling, but after driving around town for the noodles my parents wanted then receiving that voicemail, I didn’t have the energy to talk or argue with them. So I figured I’d be petty and let them use all their energy and waste their time calling me. I have a newborn who is taking up all my time at the moment so it’s not like I’m on my phone a lot to where it’s disturbing me. Anyways, AITAH here? And what would you do?
