Last month, I noticed a $15 charge from an apparently legitimate business that I had never heard of and never done business with. They sell data management software. I can't imagine what they would charge anyone $15 for, and I have no possible use for what they do.
So, I called the credit card company and disputed, and they accepted my dispute and removed the charge. I sent email to the customer support portal of the apparent perpetrator, and received no response.
Unless this is some convoluted misunderstanding involving a legitimate charge routed through an incomprehensible path, there's a crime in here somewhere. Should I leave it to my card issuer to deal with?
