Review the double charging

On the 26th of April I made a mistake of using two different bank cards on one trip, one when I was leaving Sandton and the other one when I was exiting park station and I immediately realized the error and communicated it, and I was to wait for the debit to take place and submit a claim on both cards, of which I did, on the one card there sufficient funds and on the other one there wasn't, on the one with sufficient funds the claim was successful of which the money was paid back, with the trip fair of R75 deducted, and on the one with insufficient amount the claim was unsuccessful leaving to card with -R250 and blocked, all I am asking for is for that - amount taken away and the card unblocked since I have paid for the fair and I have been at pains trying to explain this to one of their agents with no success.....
