Void a charge

Can a charge be voided (as opposed to refunded) on the same day?  A card was double charged instead of refunded thru ticketing. I'd like to void this additional charge. I am under the impression that voiding the charge will remove the charge/hold on the patrons card, since it is the same day (our cc swipers used for merchandise work this way.)  An insight would be helpful!
