Taken for a ride (not a paraglide)

I booked and paid for 2 tandem paraglides on 10 February 2025 as part of my husband's birthday present. I advised Paraglide Africa that we live in CT and are available to jump any morning during the week or over the weekend. Their communication is shocking. I had to keep following up with them and asking if conidtions were right for a jump. They have now gone silent and I can't get my R3400 back. My emails get bounced back and Whatsapps just don't get answered. I'm beginning to think this is a ****.
