Daylight ******* via technicians MM Electronics!

Samsung referred the technical fault that my washing machine had to their associate tech team MM Electronics. Who came to fix the matter after I had paid R870. Upon viewing the machine they said an element of the machine was burnt and they would need to replace it and this would cost me R2600. The one technician cautioned the other that if they made this change this would cause issues with the machine. The issue with the machine prior to them coming was that the machine was cutting off power mid cycle and would therefore switch off mid cycle but we would have to turn off the plug and on again for it to continue working. After the technicians had changed the said burnt element and I had paid the R2600. I returned home to machine that was not draining the water in the drum that the technicians had left to run and we could open the washing machine door despite the lock sign on the screen was on! The technician came back the next day and claimed I would have to pay more money for another element now! This is absolute nonsense and daylight *******. Samsung is clearly sending technicians who have no clue of what they are doing to learn on our appliances! I will not pay a single cent more! Best you take me back to where I was when I first reported my machine faulty and return my money whilst at it!
