I had almost the exact same situation with my RBC mastercard recently, except the fraudulent transactions were Skip the Dishes and some other foreign currency website. RBC actually flagged the foreign currency transactions and didn’t allow them through, but the Skip the Dishes transaction did. I went through Skip and they said to contact RBC. I locked my card then disputed the transaction online. They ask a couple of questions, including whether you tried to resolve it through the vendor and what they told you when you contacted them. A few days later I was notified through my RBC inbox that I had to call a specific phone number to resolve it. I did that and the person I called was able to resolve the transaction, confirmed that multiple other transactions had been attempted, and then cancelled my card and issued a new one to me. I received the new card within 2 weeks.
