Unresolved Billing / Refund

I made a reservation online (https://www.tsogosun.com/) in october 2017 using a credit card, on the day of arrival, when we were suppose to check-in i found that i didn't have the credit card i made reservation with and as a result we couldn't check-in, i had to pay another R4600 on the spot and told that in order for me to get refunded the money taken from the online transaction(credit card), i will have to send the credit card image to ********** of which i did. Its approaching two weeks and no one has ever contacted me regarding this and when i call iam sent from pillar post and put-on hold for the front-desk manager with no response.Even when i leave a message with one of the stuff, i never get a response call.
