Smart Satellite DSTV installers

I used Smart Satellite DSTV accredited installer to fix an error on our DSTV (ERROR 148) no connection. The companies owner - Liam - *** he has done work for me before and I was happy to re-use his services. They came out and cut the cable at the dish and just replaced 1.2m of cable with a join outside. They stated that they replaced 20m of cable. This was a lie and when I got home, the DSTV was still not working. He agreed to send out the technician again in the morning to resolve the issue, they just adjusted the connection and the DSTV was still not working 100% with channels freezing. When I called him to try and resolve the issue, he became very aggressive and started swearing at me and my wife, stating we are *****, cheats and rogue's. He fired his technician on the spot, and sent me derogatory messages on whatsapp saying it is because of people like us that small companies are failing? I was calm and treated him with respect the whole time. I did not once run him or his company down, but he was abusive and swearing. I told him I want nothing to do with him or his company and will get a new installer to fix the problem. I had already paid him R1,600 for 2.5m of cable. The new company was more professional and after spending 2 hours at the house, relaid more than 20m of cable that was still corroded at a cost of R800. (new company Mike TV Services) I think Liam and Smart Satellite are disgusting to treat their customers like that and should not be accredited or associated with DSTV at all. BEWARE of this company and particularly LIAM, he is rude and abusive and doesn't know what customer service is all about.
