Keeping my refund since 8 month

I need to share my experience with The Farm Inn and the manager Dewald Maritz. I booked the guesthouse for my clients from Germany with arrival in April. However, they had to cancel in March 2020 due to Covid and the border closing. I have had already made full payment for my clients and asked Dewald for a refund. Today 8 months later I have still not received a cent from them. Various times Mrs. Dewald Maritz advised that they have a court case and can only pay back once he knows the outcome of the court case. I have sent him an email a few days ago to advise that there were no cancellation fees applicable as according to the properties terms and conditions cancellation fees are only applicable 14 days prior and my clients cancelled 22 days prior. He never responded to my emails. Today I have sent him a Whats app and he blocked me without responding. This business should be closed down with this business ethics. To withold refunds and payments from customers and clients is ******* and is actually frad. No communication whatshowever and if you confront Mr. Dewald Maritz with facts and his own terms and conditions he blocks clients on Whats ap. They dont even make any effort to get in touch with you they just block their clients on Whats app and never respond. It is a disgrace that someone is allowed to operate a guesthouse and restaurant.
