CVwizard Charged My Card Twice for the Same Transaction

On Sunday, 2 August, while using CVwizard on my mobile phone, my card was charged twice for the same transaction. In total an amount of 6,947 was debited, and one of these charges is an extra, unjustified debit. Today, the same problem occurred again and another payment was taken from my card for CVwizard, even though I did not intend or expect a second charge. As a result, the total amount taken from my card due to these charges has reached 13,886. I have not received any explanation or support from CVwizard regarding this issue so far. I also have bank notifications clearly showing the transactions, the dates and the amounts taken. I request that all extra amounts taken due to these double and repeated charges be urgently refunded to my card and that I be informed in writing once all refunds are completed.
