Bad service from Plumb Ambulance

I got Plumb Ambulance to fix the drain at my back door that was overflowing on 24 January 2023. They came out and got it"fixed" in about 15 minutes. All they did was to plunge a wire contraption into the drain, move it up and down, and water level receeded. Two bottles of drain acid was poured into our drain and almost a R 1000 later, for 15 minutes, they left. No blockage or anything was removed or checked. One day later everything surged to the top and overflowed again. When I contacted them today the excuse was that we through food down the drain, apparently they saw some fat in water, that is why the warranty on the jobcard of 48 hours is now null and void. Really? We have never ever done anything like that, anyone with brains would now that. The warranty only says : Drains carry a 48 hour warranty. No other excuse. I would have to pay again if there were to come out again. This is a clever way of making money plus you don't even have to do your job properly the first time. So please don't use these guys! They are scamsters.
