Customer Alert – Important Notice Regarding Unauthorized Credit Card Charges

We have become aware that individuals from various countries have reported unauthorized credit card charges appearing on their statements under descriptions containing the name "Avantgarde Service" or similar variations.

Avantgarde Service d.o.o. (Croatia) is not associated with these transactions.

We are a licensed travel agency based in Croatia, specializing exclusively in travel-related services and destination management within Croatia and the wider Balkan region. We do not sell physical products, subscriptions, digital services, or any other consumer goods.

For clarity:

  • We provide only travel and tourism services.
  • We do not offer our services through online marketplaces, shopping platforms, or third-party purchasing portals.
  • We do not process customer payments by credit card.
  • Our accepted method of payment is bank wire transfer only.
  • We do not initiate charges to customer credit cards.

Over recent months, our company has received numerous emails, phone calls, and messages from individuals regarding disputed credit card transactions. Following consultations with our bank, IT specialists, and the relevant authorities, we have found no evidence that these transactions are connected to our company, our banking systems, or our operations.

If you have discovered a charge on your credit card and believe it may be fraudulent, we recommend that you:

  • Contact your card issuer or bank immediately.
  • Report the transaction as unauthorized or potentially fraudulent.
  • Follow your bank's instructions regarding chargebacks, card replacement, or fraud investigations.
  • Do not send credit card information to us, as we are unable to investigate transactions that were not processed by our company.

Please note that while we sympathize with anyone affected by unauthorized charges, we are unable to refund, reverse, or investigate transactions that were not conducted through our business.

If you are an existing customer of our travel agency and have questions regarding a legitimate booking with us, please contact us directly using the contact details provided on this website.

Thank you for your understanding.
