Deposit stolen: Theft under false pretenses - stay away from this company

Signed an order for the delivery and installation of a swimming pool cover on 30th November 2017, paid a 50% deposit with a guarantee that the cover would be installed by 11th December 2017, then the 14th and finally, a notice on the 18th Dec to say that it cannot be done in 2017 at all. It's now May 2018 and I still haven't received either the pool cover or my deposit back. I took the co-owner, Nico Basson, to the small claims court on the 2nd May, judgement was served against the guy to settle the amount owed by today but he still hasn't done so. I am one of many victims this guy has 'stolen' from but I will not let it rest until he has refunded me in full.
