Greedy card services

Nedbank decided to charge and add an extra card on my account in the middle of the month without my consent for R185x2. Two Months ago I replaced a ****** card on the money app, nowhere did it say how many charges there will be and on the 11 June they deducted the fees for that. I have phoned, and the customer support could not determine what happened and had to escalate it to a higher authority with the promise someone will phone me back. Surprise, no one phoned.
