Not paying suppliers for work performed

We supp**** HF Developments with a garage door motor for his client at the Ebotse Golf Estate in March of 2019 Since then to now November 2019, we have made various attempts to contact the customer Hercules Van Vuuren to settle his account. We even resorted to calling his client regarding our balance due to us. Since then he has not made any attempt to pay us for our services and has also caused us financial hardships. Be careful when dealing with this person and business, and make sure before providing and services to them.
