Bad service from speed queen technitian

I have a speed queen washing machine that had a problem. On the last cycle it spin and then it is suppose to stop to hang your washing.The mashine start to fill water on the last cycle when you take your washing out to hang,after the machine finishes the total cycle.It looks like the spin cycle did not work.Close was still wet machine add water on the spin cycle.I went on the internet and find JHB appliances telephone number as a Speed queen repair agent. I called the office and the lady said the technician will contact me. On 16/04/2021 the technitian Chris from JHB apppliances called me and I give him my address. He explain to me that there is a call out fee if we decide not to accept the quote of R500.He test my machine and told me that the timer and the pressure switch needs to be replaced. A three way timer he quote me R950, pressure switch R1600. Labour R1000 as he told me he also change the gearbox oil (verbally) not written on the quote. The quote add up to R3550.00. And he gives me a 12 month guarantee. I request to pay the money via eft but he insist he wants cash. I pay a deposit of R2550.00 and agree to pay the rest on completion of the job.Chris then start messing me around with the time when he will repair my washing machine.First he had to wait for spares. Then he had car problems everytime a difrent story. If lost work because I had to arrange for Chris to repair my unit and wait at home, then he ended up not to keep to his appointment prommiss.This was going on for days.Chris then eventually arrived at my house on 24/04/2021 16:00 pm to repair my machine.Chris stripped the machine took the timer apart and assembled it several times, replaced the valve. After about an hour and a half plus minus did not check the time they were finished,Chris told me I must not use my washing machine because the motor tripped. Because of continuous testing. Chris then instructed me to wait an hour for the motor to cool down as it have an protection device to protect the motor.Chris ensure me that the machine was fine and it will work perfect. As I trusted him as a speed queen technitian I payd him the balance of R1000. Chris gives me R200 discount because he did not change the gearbox oil an I accept it.So the amount I pay was eventually R800 and not R1000.The total payd to Chris was R3350.00.Then Chris left told me the washing machine will be fine after the motor reset it self.After one hour my wife want to use the machine it only allow water running in. Nothing else worked. No cycles at all.I then call Chris told him the machine is not working. He arrange to check it out on the Tuesday . Again he did not keep his prommiss it was very inconvenient for two week we had to make a plan to do our washing.Then after several phone calls and promises that he did not kept I phone his office and the lady said she will speak to him. After that he asked me not to report him as he do not want to loose his job.I told him I want my money back because. I also went to buy another speed queen washing machine.I still have the old machine that he damaged. Up to today's date Chris promised to refund me and noting hapend. The money we payd Chis was honesty hard earned. There is no way that anybody will pay for service like this. Please help what can I do. JHB Apppliances Tel:*** Technitian : Chris Cell : ***
