Hyperli went AWOL on me

On Monday, 23 December 2019 I bought a 130Minute Pamper Package for Two voucher for R499 at Bodyframe Beauty Clinic on Hyperli website. I sent them an email saying that I would like to cancel the voucher, reason being my dissatisfaction when I saw the “beauty clinic” that it was not as advertised on hyperli website.

Hyperli need to do some checking on the venues that sign up with them, I need my R500 worth of voucher, the said to me "Gift Vouchers retain their value and can be used on all of our deals and will be available in your Hyperli account within 3-5 days" it's been 11 days now.
