Dis tasteful Service

I bought a deal on the Hyperli site, received communication and my voucher no issues. Service purchased was Pilates Classes at Zilwa Physiothe******. I attempted multiple times to make my booking as Bookings are essential. Followed the whole process but no response. When I was about to give up, I received a call from family member/business associate of Zilwa informing me that She (Merchant) passed on 2019. And I should contact Hyperli.com to request refund. Upon requesting for a refund, I was hit with "Cancellation Policy". I did not cancel anything. The merchant has been deceased for over 4 years. I had expected to be re directed to another merchant but No,

This is the response I got from them:

{Hi n0ntu12@icloud. com,

After having assessed your request, I’m afraid we’re unable to process a cash refund. As per our Cancellation Policy, all refunds are processed in the form of a Hyperli gift card which is immediately available and valid for 3 years from the date it was issued. Please refer to the below paragraph in our Cancellation Policy: If you are eligible for a refund, it will be provided in the form of a Hyperli gift card. You will receive a gift card equal to the value of your purchase, and it will remain valid for 3 years.}

Why would I want to buy anything from them after this? I will never use their service again.
