HINTAPP.COM Keeps Charging My Card Daily Without My Authorization

For about two weeks my card has been charged every day with an amount of approximately 5.42 RON by a company appearing on the statement as HINTAPP.COM/US Wilmington USA. I did not knowingly subscribe to any service from this company and I did not authorize these repeated daily withdrawals. Because of these unauthorized charges I was forced to withdraw all the money from my card in order to protect myself from further deductions. I am very dissatisfied with this situation and I am worried that the problem may get even worse if it is not stopped immediately. I request a full refund of all amounts taken from my card over these approximately two weeks and the complete cancellation of any subscription or service linked to my card. I also want my card details to be deleted from your systems so that no further charges can be made in the future. I kindly ask you to review this situation urgently and inform me in writing about the actions you will take.
