Poor service and policy implementation

About Flysafairs cancelation policy that they explain on their site=it states that option 1 you can have a free change where you will not be charged. How then is it possible that you state this but continue to charge me on my return flight. I have then tried to take the voucher option but you don't even provide us with information. The next thing I see my booking is canceled. I did not want to cancel my booking. Now your site to access the booking is invalid? I tried to call your customer care it's an extremely long waiting period? You knew that you will have alot of queries after your cancelation of flights but your system can not assist us. What do you want me to do now?i still need my flight to be booked. Why are charging us but your policy says changes are free to make???
