Invalid voucher no M7R5X7 issued to me by FLYSAFAIR for my canceled flight now I'm being sent from pillar to post. An unnecessary time consuming struggle just to get a valid voucher to use for my daughter to get back to school in Cape Town!!! Why flysafai

Entered wrong date for flight booking for 30th Dec (wrong date 30th January) when we landed at King Shaka we were directed to flysafair client assistance desk there the agent dialed for us to speak to someone who will assist with cancelation. And refund to flysafair wallet (minus R300x2 )for use in future booking and I received voucher number and pin. Now when I enter it it says voucher not found when I called I'm told it's for change back to original date not a cancelation what nonsense is that why would I travel to Durban in Jan to do what exactly? I've already paid over 3.5k on charges for edits on that itinerary which was only for 3days in Dec now they wanna rob me of my 2k minus R600 when I call the callcenter I'm told to email *** there I'm told to speak to a consultant they are the only ones who can assist with reissuing a valid voucher I can use for my daughters flight this weekend back to UCT and it's am urgent matter but I'm sent back n forth between. Agents who are not assisting me with getting the voucher this is a serious disservice from flysafair
