If your suspicions are confirmed, it means the person has stolen either your Facebook, iCloud, or Google account login credentials, or phone number.
In the first 3 cases, you should contact Facebook, Apple or Google directly.
If you log in using your phone number, this means that your phone has been stolen, or that you have shared your login credentials with a third party (which is against our Terms of Service).
Either way, please contact the Customer Service as soon as possible so that they can block your account (after securing your Facebook, Google or Apple account first if you log in via text message).
Please enter the details of your request. Someone from our support team will get in touch with you as soon as possible.
Thank you for contacting us. We will do our best to reply as soon as possible.
