Over charge(I feel ******)

Good morning On 31st March 2023 afternoon I was traveling back from Midrand to Rosebank. At midrand I topped up with R50 using my ABSA debit card. At Rosebank I mistakenly tagged out using the ABSA card. Luckily there were gautrain staff members with hand held transit card scanners. I mentioned my mistake I was then advised to tag back in and tag out with the gautrain transit card which I did. However gautrain charged R200 for tagging out another R200 when I tagged in and charged my trip fare from the transit card. And wanted to deduct further R400 as penalty. Why am I penalized for rectifying a mistake in seconds?
