Worst service ever

I'm soooooo angry and annoyed at the treatment I received from Babies R Us, I bought items online which were clearly marked down, this morning I log into my emails and get an email from them where I'm told that the system updated wrong prices, how is that my problem? They don't even have a decency to call me and explain that error instead they go ahead and close my order... This is unacceptable, they are the ones who marked the items with those prices not me... I don't appreciate the way they handled this whole situation
