I participated in a masterclass, which was organized via the Zoom platform. As far as I know, using the Zoom platform is free, while my operator charged me PLN 328 for international calls, just in connection with calls made via zoom (connection hours coincide with the hours of watching the live webinar). As far as I know, none of the other users of this event had a similar problem. I would like to add that I was making a call from Poland and the host also hosted the event from Poland. What can cause such a situation? What can I do at this point? My operator (play) has informed me that I need to contact zoom.
