Stay away from Mordy du Preez LHN Services

Stay away from Mordy du Preez from LHN services. Mordy du Preez from LHN Services had to install an aircon at my premises. The aircon was tested by him. He confirmed that the aircon was working. That was beginning 2020. He started with the installation and he blew the motherboard. He also took our portable aircon with him to service. I have not received my portable aircon back, and I have an incomplete broken aircon in my office. He promised to come 16 March 2020. Nothing has been done since. I have send him emails and whats apps. I send him one again today. He is online but no response.
