So one of my friends invited me to a paid event that cost $10. I paid that at the time around two days ago through PayPal. However since then they have changed the event cost to $0. This seems a bit shoddy to me. Do you guys think I am entitles to a refund? Should I do a charge-back through PayPal?
EDIT: I have contacted the event organisers and they have provided a refund.
What is the event and why did it become free?
