Where's the Customer Service?

For the last week I have been dealing with some lousy phone customer service. I won't get into who they were; at least not yet. I'm not out to bash anyone, but whatever happened to the days of professional practice? That do include being polite, right?  Well, I've been through it these last few days, and to top it off...what is to be delivered to me , has still not arrived, although through my tracking the item, waiting on for a week, running from the back of the house to the front, in anticipation of the item....the tracking message now tells me my still not delivered item has been delivered.  WHAT!!!!  And the untrained customer service, tells me hold on!  For forty-five minutes...and I held on like an idiot!  ARE YOU SERIOUS!!!!!   This is so ridiculous it's funny...

so, am I being over the top, or am I justified in my frustration?
