Wow! The bike shops screws up with your wheel build, taking 5 months to build a wheelset not to your order then claiming that they did YOU a favor. And yet, you accept their obvious blunder with a cordial thank you. Come on! I don't mean to be rude or anything, but please get a backbone! Step up to the plate! You deserve better! Go back to that shop, have them do it right, or get your money back. It's that simple.

If the shop really wanted to do you a favor then they would have
1) Told you it was going to take 5 months to get to your wheelset
2) and recommended a different set of spokes and spoking pattern BEFORE surprising you 5 months later after de fact! That is what any competent bike shop would do. What bike shop was this???
