No I get it. That probably is the best way to handle it. I just thought while I was commenting on what I thought was going on I should share what I, personally would do in the situation. I guess I prioritize knowing for sure what the problem was as high as customer service. In this case I would say there is an 85% chance brushes solve the problem, I can't help but take that bet so I know.
But I'm sure my boss would agree with you.
