I was in the room from the broadcaster (name given). We agreed for 350 tokens first, that she would do a show for me, after she complained that she wanted big tips, instead of the smaller ones I gave her, I followed that up with another 300 tokens, of which we again agreed to do a show. In the end, she didn’t do/show anything. She took the 650 tks and banned me!

You would need to report this matter to support@chaturbate.com and give them as much information as you can including the time it happened. They ‘should’ give a refund & send a warning / ban the streamer once they have investigated the matter.
