Experience Days is an experience I wish I never had

Bought a paragliding gift voucher for two from https://www.experiencedays.co.za/ . Valid for 3 years.

Had to cancel it less than 24 hours after purchase. Requested a refund. Experience Days acknowledged refund request, promised to process it within 5 Business Days. 3 weeks later - No refund, no e-mails no phone number to contact.

Avoid ExperienceDays.co.za like the plague
