Who cares what the person at the customer service counter thinks? In six months s/he won't even recognize you!!
OK, as an aside, I'm really sorry this happened, not only are you actively trying to lose weight, but when you know you're overweight and even if you didn't cause the scale to break, it has to hurt your heart. I'm sorry. Please, don't let it get you down, you know you arent at the highest weight limit and even if you were, the scale should read an Error msg, not break.
