Bikes are medication. Rather riding them is.Just not true. Sounds like the communication could have been a bit better, but the reality is this is fairly common among many (all?) - particularly this time of year with new models. The fact that your buddies got bikes in two weeks doesn't make that any less true.
I don't see the point of a temper tantrum. You know that you won't have the bike until October at the earliest, December at the latest... If that's not OK for you then move on and find something available sooner. It's really that simple.
You talk as though this is some life-saving medication you're waiting for... It's a bike, which is a luxury item. I get that you are a paying (good money too) customer but at the end of the day it's really just not worth getting so riled up about - buy it or don't.
That said a stumpjumper is a better option as they are available and have a threaded bb
