Ridiculous Refund Policy

We called Computicket on Saturday 16th December to cancel our tickets for Evita. A 50% penalty was payable (R450 of the R900 we paid). I gave the agent our credit card details (including CVV number) for the credit to be done. Today I see that they have debited a further R450 from our card! I called the Call Centre only to be told that they first debit you with the penalty fee and then refund the full amount onto your card which could take up to 7 days! I have never heard anything more ridiculous in my life! I did not give permission for the R450 to be deducted and so they have in effect **********ly debited R450 from our card using information given for the purposes of refund! I spoke to a supervisor who said that the agent should have explained the procedure which he didn't. How on earth do you debit someone with a penalty before you give them the refund. If that is the policy it should happen simultaneously so as not to put us out of pocket for however long it takes to refund the full amount. I am sure that this has to be in contravention of the Consumer Protection Act and I intend reporting it as such.
