I will never use Travelstart again

I booked a return flight to accompany my husband on a trip for a workshop. The dates for the workshop were provisional hence I payed extra for flexible travel dates on my ticket. The dates for the workshop were changed and when I tried to change my booking I was informed that I’d need to pay in an additional amount of R12000 to change my ticket despite having bought the flexible travel dates product which Travelstart offers. After hours on the phone with Travelstart I was sent the exact same email except now it said I had to pay in an additional R8000. Frustrated, I ended up cancelling my ticket and receiving only 1/3 of the amount which I spent on the ticket but just grateful to not be traveling with Travelstart!
