Impossible Call Centre!

The new Vitality Travel website through Discovery bank is excellent, with all the new airlines, etc., available. I booked my first Airlink ticket but didn't receive a receipt for the payment made that I require for our company expenses. One can't download one either. I tried to call the call center - terrible service. They only answered the phone after 37 minutes. I enquired about the receipt, and the lady asked me to hold the line. In the meantime, I was buying more airtime! After a total of 41 mins holding the phone gave a ringtone again and got answered by a voicemail to say the person wasn't available-thank you for calling, and the call was ended. This isn't acceptable, Discovery. Please call me back and sort this out; I will not hold on for another 40 mins. My Trip ***.
