Non-delivery, but somehow my problem?

My package was supposed to be delivered yesterday. At around 2pm, I noticed that the tracking details said that it was a non-delivery, with an email following at 7pm saying that the business contact wasn't available, and that I should correct my delivery address. My delivery address is correct, but I received no call or notification from RAM stating that they were at my house with my delivery, but rather just left and left me with the problem of sorting out a non-delivery that I paid for. No message attempting to schedule a better delivery time or opportunity for another attempt of delivery

When attempting to call their customer service center at 8 this morning, when they should be open, I am met with the "high call volume" and music for nearly half an hour. When I called at nine, I received the same message, followed by a horrible dial tone. When I called back, it simply said that the line is congested and hangs up.

Do you then have so many complaints that your call center can't keep up?
