My husband and I bought tickets for the AC/DC concert for March 14 and they are canceling the concert or rescheduling for a later date however, they will resume with a guest singer! Although, I understand medical issues happen I did not pay this much money to see a quest singer for top dollar prices! They are trying to force us to take a rain check although AC/DC says can keep tickets or have refund! Will never do business with them again!
