UPS Stole My iPhone15 Pro Package

I placed an order for the iPhone 15 Pro on Sept 21,2023 which I paid in full. I get an email from T-Mobile with the tracking number on the 25th. On Tuesday, September 26, I get an email from UPS saying the package will arrive that day with a delivery window between 1:45 and 3:45pm. So I make a UPS account to access the tracking map since I have to be home to sign off on it. I see the truck in my area making deliveries on other streets. The truck is getting closer to my street but for some reason it skips my house and goes to other streets. I'm thinking it'll come back since it's not that far away, but it just gets further and further until the truck is back at the warehouse. I was patient knowing things like this happen, and the next day the UPS tracking website says "The delivery date will be provided as soon as possible". This gave me flashbacks from last year when this happened to my macbook delivery from apple.com (which took a month for me to receive it). 

Today on Sept 28th, I contacted UPS who looked into the shipment...apparently it was stolen according to them and they told me to contact T-Mobile. I call T-Mobile, and the lady said that she'll give me a call back in five days which is Tuesday, October 3rd.

Should I file a claim with ups now, or wait until I (hopefully) hear back from T-Mobile on Tuesday. And if this happened to anyone else, how was it resolved?
