My item isnt here yet and idk if im overreacting

So i bought a game for my dads birthday, it said it would arrive around august 6-8. Then on august 3 i received a tracking update that it arrived in a PO box near the sellers end.

I assumed this was a mistake and it would probably update by the next day, when it didnt i sent;
“Hi! I bought this game the other day and i just wanted to make sure it was still on the way to me. It says it was delivered to a PO box in #### yesterday. Thank you :)”

On august 7 they respond to me with what im assuming is a copy and pasted message;
“Hello, I am sincerely sorry for the mistake in tracking information. My local USPS scanned in 46 packages they wrong way and all of them show as yours does "delivered at PO Box". I have been assured by multiple supervisors that within their internal system it is showing the items as moving. I know this is frustrating for both me and you. Please know I am doing everything possible for them to update tracking. I sincerely appreciate your purchase and patience as I work as hard as I can to keep all of my buyers updated with all the information I have.”

I wasnt really sure what to say so i just waited a couple days for the tracking info to update, on august 9 i sent;
“Hey, i havent seen a tracking update. It still says it was delivered almost a week ago. Is there any update i can get from you”

Then another two days passed, and on august 11 i sent
“Hey, i havent seen a tracking update. It still says it was delivered over a week ago. Is there any update i can get from you”

At this point im not sure how to move forward, i havent gotten a response since august 7 and i dont think they even read my first message. Im tempted to click “item not arrived” and just get a refund. But id rather get the game and move on from this.
