I do think it was wrong to phone and change it without him knowing. You let him think he was getting what he wanted when he left the store if you really wanted the other suit you should have told him it was your choice since you were paying for it. (but I don't think it should be) Its HIS prom and he should be able to choose whatever he wants to wear its not anyones choice but his. Would you do this to your daughter and a dress she chose that you thought wasn't great?? I doubt it. Good luck and I hope you can call back and change the order again.
