Wow I am annoyed (USA-hotstuff)

Not only did the shipping took longer than they promised, my order arrived today and I actually got the wrong flashcart!. It took a little over a month since placing down my order to finally have it delivered but with a lot of complication such as my tracking number they provided didn't work for 3 flipping weeks! I ordered a SuperCard DSTWO and they flipping gave me DSTWO Plus 4 in 1.

Now I owned a SuperCard DSTWO previously, the kids lost it somehow which annoyed me to go purchase a new one. I read around gbatemp and usa-hotstuff was a recommended site to order since it had a reasonable price. The box of the DSTWO plus was half the size of SuperCard DSTWO and it didn't come with the MicroSD package that I put down for extra!

Anyone know if their customer support is competent?
