AC/DC concert postponed due to illness of lead singer. They are going to replace him. We would never have bought tickets without lead singer period! After many emails and phone calls talked to someone that said we have to review details and hung up on me. Found out after my credit card co. Called them no refund because they were still touring as AC/DC. Got an email telling us we could try and sell our tickets ourselves but prices go up and down so we probably wouldn't get what we paid. We would be lucky to find anyone that would buy it I'm sure without lead singer! Letting our credit card company deal with this horrible, untrustworthy company.
