Computicket should not sell tickets to high demand events - their infrastructure is not up to it

Tried to get tickets for the Federer/Nadal match. Logged into the site as soon as it would let me. Got stuck in the waiting room. When I got the chance to purchace tickets the controls didn't work - I was stuck with a message saying I was trying to order too many tickets, even though I was ordering less than the 6 allowed. I tried different tiered tickets - same response. After lots of frustration it became clear something was going wrong on the site, and it just wasn't possible to buy. Could see the available tickets getting fewer and fewer as I was desparately trying to get the site to respond. Worst experience ever.
