Fradulent charge by BP Garage

On the 2nd of March, I went to BP Soshanguve Block BB to Fill up with R200.00 Fuel and Paid By card, Then I was charged again on the 26th of March R200.00 with the same reference of the 2nd of March.

I went there and showed them proof from my phone and I asked them why they charged my card, this is fradulent.
