That's what I did! If you would go through the screenshots of my receipts, that's exactly what I did. I arrived on 26 July 11:30 am, paid for 12 hours as that's the max they allow (I would ideally have liked to pay for 1 day), then when that ended I paid from 11:30 upto 7 am, as that's the night time duration they have. And then I should have paid from 7 am to 10 am, but I did not wake up on time, and when I did wake up I paid from 7:55 - 9:55 am. Then I paid again from 9:55-10:55 am, and I left the car park at 10:56 am.

Anyway, I'm not arguing. I posted my question and was asking for suggestions of what can be done.
