MM-All Electronics - Shocking Service!

I reported my washing machine which stopped working suddenly on Friday 14th September. The agent MM-All Electronics were quick in sending a technician out on Monday 17th. The problem was the motherboard which the technician told me was 90% of the problems so he wanted to bring a new one with him but they were out of stock. He had ordered it and would be back the following morning to replace it. (The machine is still under warranty). 12 days later I am still waiting for my machine to be repaired. It is no fault of the electrician but the customer service/feedback from MM-All Electronics was appalling. Every time I called for an update on the spare part I was told they would phone me back in 2 minutes which never happened. I would always have to phone them back. The last time I phoned on Thursday 20th and actually got put through to a customer service person called Petro he was initially very helpful and promised to call me back in an hour but didn't so I called him. He insisted he had but couldn't get through which was nonsense as I was waiting for his call and had I been on another call, I would have had a missed call and surely he would have left a message. He was so rude and constantly spoke over me while I was trying to talk. On Friday I received an automated message that my repair has been cancelled. I then got another message with another reference number. Apparently Samsung handed the repair over to another repair centre. So 12 days later and my washing machine is still not fixed. I am absolutely disgusted by the lack of communication and customer service from MM-All Electronics. They should change their name to F-All Electronics & Customer Service!
