I like ups. They are one of the biggest airlines in the world, deliver incredibly fast over incredible distances, but

Fuck their website!
At least they've updated the design but the functionality is just garbage. I wanted to track a package that is on its way to me. And I wanted the delivery person to know that he could put the package in the garage if nobody is home. I had to register for two different services (God knows what's the difference) and even then ups somehow knew an old address (I believe I managed to get stuck there In the past) which I couldn't remove. I found the option to tell the delivery person to put the package in the garage in some random menu but I don't know if it is for the right address or package.
Why is it so fucked up? Everybody else (DHL for example) has a decent site on which all the stuff is easily manageable.
