30 mins waiting to speak to customer service!

I called the call center to talk about a package that should have been delivered, I received a voice mail saying I should call this number. 25 mins before I was put through to reception, another 10 mins on hold waiting to be put through to customer service. then customer service **** and said that they were at my office to deliver and no one was there, we have 40 people in my office that would have been inpossible, they confirmed it was during office hours but cant tell me when. ridiculous service.
