Pathetic!!!!!!!!!!!

Pathetic, absolutely pathetic. They changed my flight three times, without notifying me, and then when I ask to be out back on the original flight they said sorry it is booked out. I got pushed off a flight I booked for, and then I asked for a refund and they said sorry we can only give you a voucher. What must I do with a voucher for an airline I will never used again?? And guess what, I will not receive any feedback from Flysafair, because the customer comes last with Flysafair!!!!!!!
