I have to disagree with this. In my case, the only way I was able to get it to anyone to actually look at it, was to dispute $5 of my charge. A charge back costs the company. The banks bill the company for a charge back, that they would not have had to pay if they had just refunded the $5. This tends to get upper managements attention, if they have too many charge backs.
