I can actually understand the in-store rudeness better than the online shopping inadequacy.
For the stores- they hire local teenagers who may or may not have a particularly good work ethic.. (Not saying that is right, just that it is so common). That said, I agree notifying corporate of the problem is a very good idea (even if it only results in an admonishing email to the store manager)
I am more surprised at how crappy their online customer service is. The two times I have had to call with an issue, I was on hold for way more than 20 minutes on each occasion, and the person did NOT solve my problem. I have also tried emailing customer service. Once I got a response after SEVEN DAYS- the last time, no response at all. This last time, I tried contacting customer service through their facebookpage. They actually got back to me within a day which was a shock. However, they would not send me the items I had ordered (sent me 5 wrong items) until I had sent the wrong items back. Sounds easy but finding a Fedex office to take my huge box was a real pain.
Considering how many orders got entirely messed up this last time around (like 50%?) I would not be surprised if there was someone in their shipping/packaging department intentionally messing things up... maybe a disgruntled employee?
I agree mentioning something to corporate, whatever the issue is, is absolutely a good idea.
