Mr D *****elent Card transactions

Yesterday after seeing some suspicious transactions I noticed a trail of *****ulent transactions from my Mr D app from dated back from the 3rd of August till this Morning this is the only place the card details were stored and there were no traces of transactions on my app only reason I was alerted to this was the payment notifications I have since blocked my card and opens a case of ***** with my bank but I am still trying to figure out just how this compromise happened I am also form Cape Town and saw a similar complain about this so I'm not sure if the leak is only here
