Standard Bank deducting annual fees for a garage card I do not have

I have discovered that Standard Bank has been deducting R720 from my account on an annual basis for a garage card that I do not have -- and have never had! I have never ever received any communication about such a card, never received a physical card, never received a single statement, and no such card has ever appeared on my banking profile. I have never ever had a garage card! I contacted the call centre, and the latest amount has been reversed, However, I have since discovered that R720 was deducted last July too, and most likely also prior to that. I need to pay to obtain July statements for each year so that I can see how far this goes back! I have sent my banker several emails asking for an explanation as to why I have been charged these fees, but I have had no response. She simply forwards my emails to someone else and there is zero feedback. I have been a longtime customer of Standard Bank. I am appalled and disgusted! I will definitely be looking elsewhere.
