Fly By Night - Extremely ***** company

Had a new Aircon fitted in Feb 2023 by this company. informed them on 24th Nov that the Aircon was faulty. They promised to come out on Monday 27th. This did not happen. I tried calling and they would not take the call. I tried sending messages via WhatsApp, which they did not open. Eventually on Wednesday, I called from a different number and they took the call. They promised to come out on Friday by 9am. This did not happen and once again, they refused to take the calls from both my numbers. They sent me a message a few hours later telling me that they could not come because their Bakkie broke down. Since then, they have been avoiding me again. They don't take any calls and they don't reply to any of the messages. Real Fly By Night company. Busy advertising specials all over the place, but can't provide any after sales service to customers that paid them.
