Claim voucher without service

I had an extremely disappointing experience and ended up not using the voucher at all. I struggled to redeem it via WhatsApp and had to follow up multiple times just to confirm a booking. On the day I had another treatment scheduled, the salon cancelled on me last minute. They rescheduled, but the new time didn’t work, so I asked to move it to the next day. When I arrived, they told me I needed to pay an extra R250 for the reschedule — even though they were the ones who cancelled in the first place. I left without receiving the treatment.

To make matters worse, about an hour later I got a review request from Hyperli, meaning the voucher was marked as used — even though no service was provided. I contacted Hyperli to let them know I never used the voucher, but they never responded. None of my reviews were published either — they seem to only post the positive ones. Overall, very unprofessional from both the salon and Hyperli.
