Incorrect booking dates

I recently made a booking to fly to Johannesburg on the 31st of March 2019 and a return ticket to Durban on the 3rd of April 2019. I had gone through their website, selected the dates and paid on the evening of the 7th of March 2019. Once paid I tried checking in online to ensure their were no issues and the site had then still told me check in only opens 24 hours before departure. Only today the 19 of March 2019 when I was finalizing my trip I had noticed on the email that was sent to me that the dates were for the 8th of March 2019 to the 10th of March 2019. I have no idea where these dates came from and I certainly will not use the services of flysafair again.
