Non existing service Mastercare

It should be less Been battling from November last year for them to repair my dishwasher. I have logged about 5 job request and recieved job cards for all of them On the first one a idiot came out and after seversl pjone calls it was reported it were due to loadshedding which I disputed this because the machine is always swotched often and switched on to wash dishes. On the third job order I recieved a message that my macjine have been repaired although no technitian were on sight. I phoned in to enquire about this I were informed that due to rust it can not be repaired. After enquiring about this it was found that it was a another dishwasher at a different adress. A technician came out after a new call were logged. He said the element needs to be changed. I sent him the job card and serial number as requested only to be informed the job card have been closed. I created a new job card sent it nothing happened. Eventialy 4 Septemper the machine have been picked up. Phoned again on 10 October for the upteenth time and al ways I get the answer they are waiting for spare parts. It always being esculatted to management and the supplier. Do not know who the supplier is but they should get another one as it seems these spareparts are imported from the North Pole and made by ****her Christmas pnce a year. It is totaly redicules. Their service is very poor and I starting to think they take your money and looks for excuses not to give any service in return.
