Defy washing machine

I am getting disappointed on Defy technician, I have bought a machine last year May which within a month it was making a loud sound, I logged a call for it to be locked at ref: 2157911 which they did 10 months later I am experiencing the same thing logged another call last month ref: 22257073advised them I have moved and changed numbers as well they have captured all that last week I called to check on status since they have advised it takes 3 business days for them to come. They advised they could not get hold of me I then asked them which numbers are they using they gave me my old numbers then I asked them I did advise I have changed numbers and address they updated that again but now no one is even calling or coming to fix or maybe they waiting for the 19th so that their warranty expires? Sent an email 3 weeks ago to the support mail and it never gets responded
