Consumer disputes

If you have a complaint, please write to info@coreeng.eu first; we can resolve most issues directly.

In Hungary, consumer disputes are handled by conciliation boards (békéltető testület). The board competent for our registered office is the Budapesti Békéltető Testület, operated by the Budapest Chamber of Commerce and Industry (Budapesti Kereskedelmi és Iparkamara) — 1016 Budapest, Krisztina krt. 99. I. em. 111., bekeltet.bkik.hu. Consumers living in Hungary may also turn to the board competent for their place of residence.

If you live in another EU country, the European Consumer Centre in your country (ECC-Net) can help with cross-border disputes.
