Total lack of respect towards customers
Unfortunately, once more, this company proves it is not able to commit to an acceptable level of customer experience.
Even if you use the "UPS My Choice®" program and clearly define times where you are unreachable, they will blindfoldly try to deliver the parcel 3 times and then send it back to the sender.
Changing that via the website? No joy. I tried multiple times different options (holding it back, deliver to another address), but all option fail in a "log-in-loop".
Customer service on the phone? Same thing, unfortunately helpless.
I am absolutely amazed that this company still is able to coexist next to DHL, FedEx or Swiss Post.
