I had a Discover credit card while studying in the US, but I moved to Switzerland last year and continued using the card.
A few months after moving, I noticed around $800 in fraudulent transactions. I contacted customer service, and they said they would freeze my card and send a replacement, but I never received it.
Over the following months, unauthorized transactions happened again several times. Each time, I had to contact customer service using a friend's phone in the US because I couldn't easily call from Switzerland. I reported the charges and asked for the issue to be resolved, but the problem kept recurring.
Eventually, I lost access to the app after my account was migrated to Capital One. I can no longer log in or send secure messages.
I'm worried that unauthorized charges may still be accumulating and that unpaid balances could affect my US credit history. I want to close the account completely, resolve any fraudulent balances, and make sure I'm not held responsible for charges I didn't make.
Has anyone dealt with a similar situation after moving abroad? How can I contact Capital One from Switzerland, dispute the charges, and close the account if I cannot access my online account?
I'd appreciate any advice, especially from people who have handled US credit card issues while living overseas.
