Supersonic does it again, lying or *********** staff?

Supersonic debited my bank account for a 25gb topup that I paid for using credit card, I called countless times was asked to provide proof of the purchase,of which I did, lady who i spoke to said the refund request was forwarded to their accounts department and the R150 (that was added on my normal R400 bill) would be refunded to me, that was a lie or their employees are ***********.
