Shocking Customer "Care" Service

On the 23 July 2025 I made a domestic flight booking via the app. I tried to load the 2 Flysafair vouchers I had. These kept coming up as "invalid". Two other people tried loading the vouchers with the same result. Unfortunately I had no option to pay full price. On the 24th I emailed the "support" team with all necessary attachments. No response! Various emails followed & I eventually used the whatsapp option requesting to speak to a "human". This was a most frustrating process. They expect you to monitor your post 24/7 in order to engage. After a wait of 2hours on my first attempt, with no response, I had to make further attempts only to eventually be told that the Supervisor said that I could still use the vouchers for another booking within the expiry date, which happened to be 16th August! I received responses to my emails eventually & it suggested I phone the call centre. The call centre call puts you through a dozen choices & prompts & then finally you get to speak to a consultan. I was then told me they would extend the voucher BUT I had to phone with flight dates & then they would extend the voucher which had to be used within 24hrs of the extention. The entire process took 2 phone calls, 5 irate emails, & 10 or more extremely frustrating WhatsApp messages to get a final response. I think the Customer "Care" centre gave appalling service & I will most certainly think twice before using their company. It's just NOT worth the effort!
