Pathetic, unprofessional, poor service is an understatement

I bought 2 vouchers from Hyperli on the 17th of April for a friends birthday surprise that was on the 1st week on June, and it was valid for 3 months. Made an appointment via whatsapp with the service provider (THE BEAUTE LOFT-RANDPARK RIDGE) 3 days before, when I got there, she apparently forgot about my booking and asked me to come another time. I have been trying to contact the service provider via email and whatsapp and there have been no response until today when I sent her a message to refund me my money, she refuses saying the voucher has not been redeemed. Who is really to blame here? I bought my voucher through hyperli, the voucher has not been redeemed, the service provider does not want to refund me and Hyperli does not want to refund me as well? Someone need to explain to me what's going on because this is just b*****. I do have proof where I have been communicating with the service provider. STAY AWAY FROM HYPERLI AND THE BEAUTE LOFT (RANDBURG, RANPARK RIDGE).
