Flysafair's ********** customer service

I received an email notifying me that my flight had been cancelled. When I tried to get ahold of someone using the help line I waited for 20 minutes before some took my call only to be hung up on. It took another 15 minutes to get through to them again. When I told them that my flight was cancelled I was told I was wrong and my flight was still planned, I had to send flysafair proof that their own flight was cancelled before they would listen to me. When I asked for a refund I was told the manager needed to handle this and he is busy they would call me back. This was at 10am. By 2pm I hadn't heard anything so I called them again, and was hung up on again.. I finally got through again and once again I was told that I would be called back. To their credit I was called back, they called to tell me that they had no news and would call me back. The following day I called again and was put through to the person who was dealing with my complaint, he hung up on me twice, his name is Thando. He then emailed me and said I could get a cash refund if I had travel insurance or a voucher. I did have travel insurance, so I told him and sent the proof. He responded saying the flight was booked through a travel agent so they could only give me a voucher. It's strange seeing as I booked the ticket through there website. I finally told them to just give me the voucher, that was 5 hours ago, I wonder how long I'm going to have to wait.
