Additional payments

Ouch, that is an expensive phone call.   Did you see written somewhere or were led to believe the call would be toll free?  Is there a reason you chose to call the number and not use voice over your computer/phone/tablet?

Unfortunately, I think it is the caller's responsibility (you) to know what you will be charged for placing a phone call..

If you want to share the first parts of the phone number you called from and the Zoom number you called to I would be interested to try to look up why play charged so much.  What is the name of the operator in Poland you called from?

Hi, @veroniekelli.

Not that it will help you directly, but you might send this Zoom Support article to your meeting host:

If their Zoom account originates in Poland, it would seem normal that local Poland phone numbers would be made available.

I'll be honest, though: Most accounts are set up to not permit any toll-calls for meetings and webinars.  The expectation is that if you can access a local direct non-toll number, great; otherwise you will utilize the computer audio.  Unfortunately some people click on the "quick dial" number in the meeting invitation and do not notice that it may be a long-distance toll number.
