no response

I booked a ticket from Cape Town to Bloemfontein on their website. The money was deducted from my credit card, but NO confirmation was found. The nrs on the site did not exist. I mailed a letter to their customercare. Where I received an automated reaponse that they will reply if it was within working hours (which it was). They are open 7 days a week till 5pm. On the automated letter was a different telephone nr, which I also tried, but to no avail... we are now going onto 36 hours without a response...even if its office hours.
