I am having a similar issue with UPS
They claim to not have been able to find my address or there is an issue with it. I logged in and checked it, there is no problem with it. So they flagged it to be returned to sender. This is my PS5 Pro that was guaranteed delivery on Nov. 7. I called and reamed someone, now they went looking for my package and said they can't find it. It is already 6 days late.
So yesterday, we drove about 1hr away and picked up the last one we could find in local stores. The salesguy said it was his last day and gave me $25 off because I am a GameStop member, which was nice of him.
The one I am waiting to have delivered will be donated as a raffle price for our local food bank, sponsored by our company.
*Update from UPS, they mailed it back... WTF
