*****ulent transaction on a new account

I closed and opened a new account on the 23rd April because my phone was ****** and emails compromised.simple because i didn't want whoever stole my phone to access my bank account,Fnb Rustenburg mall gave me a new card and account number to my suprise on the 1st of May i notice a prepaid purchase of R50 to a number i dont know went into my app and noticed a ewallet of R500 to a number i dont know as well.immediately contacted fnb ***** and they frooze my account to minimise any further transactions,was called the following week by a consultant named Martinus van niekerk told me to get an affidavit of which i did but however i never received any feedback from him if i dont email him to check to feedback has been provided,went several times to fnb in rustenburg mall with no help. I am honestly so disappointed with the service i received from fnb. On top of that i was given an islamic account which limit some of the services on the app and that was not even explained to me.i however went to the branch again to enquire and was told to contact customer service of which again i did,changed my plan o another one,i am suppose to get a new card and i am still again waiting for fnb,all i want is my money back
