Rebooking of tickets that was cancelled

<p> worst experince i had worst call centre to ever ever to speak to they dont know what they saying. I booked ticket with them on the 19/01/2017 an withing 5 minutes i cancelled they refused to refund me so i said all good an well i will take a voucher for those 3 tickets i bought now when i speak they dont want to even provide me with those tickets an want i must provide them with a sick note for a child that just had a running stomach. So pethetic as a company to be so desperate to hold on to someone cash. The lady Pateince advise differently yesterday to giving me option to rebook which i agreed apone appose to a refund.The have a manager called Digaledi she is so rude an not will to listen actually laughing on the phone with her other useless staff their.</p>
