No ticket or pro for me!

Bought 2 tickets online for an event on a public holiday. The website told me to pick the tickets up at a postnet which was closed. No alternatives were given. When I emailed them, they responded after the event saying someone was printing tickets at the stadium. How am I supposed to know that unless it is in my confirmation email or on the website? Ticket pros have shown no effort to correct the problem, apologise, accept responsibility or reimburse me. Pathetic service and incompetence.
