Carpet not clean properly

Only 2 persons arrived at 9h00. The guy was a temporarily worker and a lady. The machines they use is not what is advertised on Facebook or what they use 3 years back. They pitch up with very old machines. The lady dump buckets of water over our carpets and scrub with ‘n big machine. Then Francois was to suck up the water. That was my first experience in 40 years that they dump buckets full of water on my carpets. He could not do it properly because he told me that there is something wrong with the machine. They left at 11h00 after cleaning 3 bedrooms, one loose carpet and 2 lazy boy chairs. That night at 22h00 we could still not walk on the carpets it was wet for 3 days. I phone Carel the owner of the business and send him photos of the problems. They came back the Friday. After I showed Francois all the places that are not clean he realised that they have to do everything all over again Then he advice to came back on Monday 25 March with Carel so that Carel can see for himself that the machines is not in good working order. Me and Carel correspond with email where I asked him if it is possible that he can pay back the R1320 cash and then I can get somebody else to do the work. He wrote me as stinky email and then I wrote back that we keep the appointment for 25 March as Francois advice. He did not respond back and they did not pitch up 25 March.
