Poor service

The worst customer service ever, l don’t know why such companies are still being used by these Airlines. I made a flight reservation with them for FlySafair on the 17 th of April from Capetown International AirPort to OR Tambo International AirPort and l made the payment through my bank card online. When done l got my ticket on my email and guess what, the destination was changed to Lanseria Airport. I quickly called them to rectify the problem but what l got there was the worst nightmare. The staff was so rude and not even near of helping. I was told to contact the Airline myself and make the changes with them, as they can do nothing from their side. I contacted FlySafair and the lady was so helpful in listening to my concerns, but unfortunately there was nothing she can do on her side as the ticket was purchased through a third party which was using a system that block them and the passengers from making any corrections or changes on the tickets. I contacted travelwings for the second time, now l was told the ticket has been cancelled and l should expect my refund after 4 weeks. On asking them why so long still there is no answer
