My wife’s just had her Mondo card details used by a fraudster and, all credit to Mondo, they’ve been absolutely brilliant about it and a new card is on it’s way. Luckily she only had a small balance on the card so the fraudster’s £400 and £100 purchases failed and they “only got away” with ~£10 worth of fraud.
However, this card had only been used at 3 retailers (all internet/CNP ones) previously - 2 of which are Amazon and HeartInternet: so unlikely to have been “leaked” from them (but not impossible).
I’m therefore wondering who actually investigates card-data/fraud breaches: is it the card issuer (Mondo or Wirecard), Mastercard themselves, the merchant’s bank/provider or “nobody”.
I’m especially interested as a few months ago my MBNA card was used to purchase car insurance (over the internet) after staying an an “apartment” in London - where I suspect the card data was exposed and whilst I told MBNA of my suspicions, they didn’t seem too particularly interested…
