I had a mysterious $150 charge on my credit card from June. I called Visa and asked what it pertained to. They said they’d flag it and that they’d be in touch. They never did get in touch, but they did reverse the charge for
WPY*Fundrazr Victoria, which appears to be a crowd funding site. Perhaps it was exploited to launder credit card fraud, using stolen card numbers?
I was also given a new card. Last time I had my card number stolen behind the scenes, it was also charged $150 in two $75 transactions.
