Hi @Nikoletann Thank you for contacting Community forum. I understand you wish to block an account whom you think they may withdraw more money from your account. I can certainly understand how disappointing this could be. Usually, you can block the contacts of your phone list. Unfortunately, there is no option to block such account on your end. Do not worry, if your account password and security questions are strong, no one can access your account or withdraw money from your account. If the charges are for subscription, you can cancel them to avoid future charge. For more details, you can login and contact us for further help. Take care! Narendar1
