Dissapointed In FNb taking care of its clients

Yesterday a online payment went off. I have not approve any payment on my FNB app. No notigication was reveived to approve the transaction. So ons this it is on my side *****. Because for amy other transaction thst I make monthly I get everytime a notification to approve payment. But now I want to ask FNB how is my money save if anybody can just get my card and start making online purchases. This is not acceptable and I dont feel that my money is save. I am very dissapointed in FNB private clients. They do not care about your money and i confirm that your money is not safe
