UPS

I've been expecting a package from Sweetwater, since the 5th of March. The package finally gets picked up and distributed via UPS; I get an email stating my package is arriving today (03/16/2021), I am patiently awaiting. I receive an email stating that my package has been ‘delivered', yet I never received it. UPS hasn't knocked on my door, nor have they requested a signature from me! The reason I know ups hadn't knocked on my door... I have a camera. I don't know where my package was delivered and I don't know who signed for it. I have the My Choice app, with my name, address, and phone number; yet I continue to have this problem... But it's always the ‘shippers' fault, as ups never takes responsibility for their mistakes. This, isn't the first time, this has happened.
