Worst Service EVER! No written warranties and threats. STAY AWAY!!!

Worst after sales service ever. I paid in full for 2 aircons prior to fitment (even though only 70% was required). After about 2 weeks, I contacted Clint Smith and let him know one AC was making a buzzing noise when off. He said he would come look ‘when he was in the area’. I had to keep following up with him and about two weeks later he came and identified the issue. He also repaired the damage to the waterproofing he had left hanging that my builder noticed. I then waited again until he had a job ‘in the area’. Once again, I had to keep following up. Finally, he set a date to do the repair because he was going to be ‘in the area’. After numerous messages on the day and no response from Clint Smith about the time he intended coming through, at 19h00 that evening I told him I would ask the manufacturer’s agent to fix it. I waited all day and by 19h00 and no replies to any of my numerous messages, enough was enough. He then left me a rude voice message stating that I was being unreasonable and that he had the part and would have come and done it, but since I wanted to involve the agent, that I could then wait for the agent to fix it. I messaged him and explained that I would have to let the people in my area know about this poor service as I had given his name to a few that were looking at getting aircons. He then left me a threatening message stating that his lawyer would be onto me if I informed people about this poor service (I still have this message on my phone). The manufacturer’s agent did the repair the very next day and even stated that Clint Smith should have repaired this unit within a week, not weeks and definitely not ‘only when he is in the area’. Two months later I asked Clint Smith for an invoice as I do not have proof of purchase and installation and as such, no guarantee on the R15K installation. He refused to give me an invoice stating that the quote is good enough and that he has 1000 clients that are happy with that. I tried to explain that I need an invoice. His reply was “All my clients warranties are on the quote…been doing the same for 10years. Definitely not changing for you. So you want another warranty. Call Brad. My client content”. So what am I? I am NOT content and I thought I was a client. Brad is the manufacturer’s agent that fixed the faulty unit and this is Clint Smith implying that since I had turned to the agent for help, I should ask them for an invoice even though I never bought the units from them. So utterly unprofessional, childish vengeance. Clint Smith and Polar Aircon do not give invoices, no warranties in writing, you will have no proof or date of installation. In short, no warranty. His ‘word guarantee’ is certainly not admissible in court if a new unit breaks. If Clint Smith stopped fitting aircons, who will repair the units if I have no proof of fitment? Not sure why anyone would do business for 10 years with 1000 clients and have no invoices? Why would anyone not be prepared to issue invoices for work done? How does Polar Aircon and Clint account for their income and expenditure? Utterly disgusting attitude and shocking customer service. I have bought lots of stuff in my life and never experienced this. Worst ever
