Scammers have gained access to your account or credit card information and are misusing it. Your account balance was around CHF 5 000 before. The scammers withdraw all of your money or make payments that you have not authorised. You report this to the police and inform your bank. Unfortunately, it is not liable for the loss. But, thanks to your credit card, you benefit from online account protection. The insurer reimburses you for the amount lost.
