Mastercare POOR CUSTOMER SERVICE

This is my second negative review I've had to post for the same repair job. I originally reported a fault with my AEG washing machine on 31st October. After having NO FEEDBACK and not a single one of my dozens of calls returned for almost a month and a half, I eventually got attention from mastercare when I posted here. They came and fitted the part I waited so long for last Monday only to discover that wasn't the problem. The original fault I reported unresolved. They then took the motor out and serviced it, brought it back on Wednesday....still didn't work. They then took the machine away with them. I have tried calling every day since to find out what the status is and if they know what is wrong and how long it will take to fix. The ladies and gentlemen at the calls centre's have all passed messages to the manager Sean Stevenson at the Durban branch who has NOT called me back. What is wrong with my machine and how long will.it take to repair?????? Can someone please returns my numerous calls. I have been a client for almost 2 decades and I have never been more disappointed with service provider. At this point I just want my machine back so I can get someone competent to repair it. Mastercare have not lived up to their reputation and claims as the leading repair specialists in the country. They can't even return a damn call!!!!!
