Discovery Bank Unable to Assist after their Security systems are compromised.

I just had a payment go off on a virtual card that I did not authorise whilst I was driving. So I call discovery ***** line. I get transferred from person 1 to person 2 to person 3. I selected ***** as the issue I am having. Not one of the people I spoke to is able to help me. They told me I have to get a letter from Apple. I mean seriously what is Discovery doing about the increase in ***** cases. This is the second time this has happened to me. And they can't help me.
