No one calls back of course. They just made it sound like they would. They made it sound like the conversation you were having was important, but "poof" they are gone. I find it disturbing to say the last. I find it rude and very poor etiquette. It is disrespectful.
To me, it really says, you don't matter. I didn't want to talk to you in the first place, but this was my only way off the phone. Of course, it doesn't matter if they called you and you're not the type of person to really want to talk on the phone forever. They just felt it was better to be rude and get off the phone with some lame excuse.
