The name of the merchant may not fully match the name of the brand or website where you made your purchases. The name of the company affiliated to Mastercard (from which we get the merchant information) is sometimes different from the brand name. Check the terms and conditions on the merchant's website to see if you come across the name there.
Unfortunately, it does sometimes happen that a seller with bad intentions has a different name than the one on the website. You may then be dealing with a fraudulent purchase. Pause your card immediately and contact us through our support channels with more info on the transaction in question.
