cannot email me tickets that ive already purchased!

I purchased tickets for a show on Sunday and collected them at a local checkers. Somehow I misplaced the tickets and called computicket to advise that I require them to be emailed to be however they say this cannot be done and a new ticket needs to be purchased.What nonsense is this? Please can some call me about this asap? Why must i pay for something again that ive paid for already?? All i need is a simple email confirmation.I know they are trying to prevent ***** or whatever , in that case give the customer the option to login to their profile and print out the tickets in such cases!! Come on guys we live in the 21st century and this shouldn't be an issue!!
