Daddy's deals sells vouchers of non existing vendors and refuses a refund

I bought a voucher on 15/09/24, which is valid until 31/12/24. On 20/12/12 I tried to use it. The vendor's email was not answered. The vendor's number seems permanently "currently not available". We drove around and even asked 5 centre management employees from Access Park, none knew about the vendor. Maybe it never existed in the 1st place. I asked for a refund same day, but Daddy's Deal is denying a refund although voucher is still valid. This is undue enrichment and a ****. Stay away from Daddy's (****) Deals.
