Santander Bank Charged Me Without Authorization

I have a current account with Santander Bank, which I have held in Elbląg for a very long time. On 9 April, an amount of 140 PLN was taken from my account, even though I am not using this service and did not expect or authorize such a charge. I do not understand why this money was taken and I have not yet contacted the bank regarding this matter. I request a full refund of the 140 PLN that was withdrawn on 9 April and I also ask for such charges to be blocked in the future so that similar situations do not occur again. I expect a clear explanation of the reason for this charge and a quick resolution of the issue in my favor.
