Postal Service, you suck!

So a few weeks ago, I placed an order with Right Stuf during their 12 Days of Anime sale. I got my Slayers boxsets just fine, but the rest of the order was sent separately. Even though that package was sent before the one with Slayers, I still haven't gotten it, so last week I emailed Right Stuf about it. They said that they couldn't do anything about it until Jan. 15th due to insurance issues, but if I still hadn't gotten it by then, they would look into sending me a replacement. In the meantime, they suggested I contact the postal service to see if they could locate it.

I emailed USPS on Dec. 30th, and the website said it would be about two to three days to get a response. With them being closed on New Year's Day and Sunday, I figured I would probably get an email today. 

Well, I didn't. Instead, I just got an offer to fill out a survey about their customer service.

Guess what, USPS? I don't usually bother filling out surveys, but I'm going to fill this one out.

Lose my package, then fail to get back to me when I email you about it?

Your customer service SUCKS!

EDIT: Okay, so I got an email from them this morning (which I guess is considered the third day if you don't count the day I sent it as the first). They were quite apologetic about losing my package and are going to try to find it, but since it wasn't a registered package, it seems like it will be difficult to track. (That's what you get with free shipping!) *sigh* Guess I'll just have to wait and see (and hope that Right Stuf still has my items in stock when and if I need a replacement. I don't think they had many left when I first ordered...)
