Defy washing machine

I have been without a washing machine for over a year. Finally after a lot of hard work and saving we managed to buy one from Metro Home in Menlyn. From the start there were problems with this BRAND new DEFY washing machine. Besides all the washing being covered in washing powder and not we did not put to much in, the leveler also did not work after spending 40 mins try to level it, hence having a very loud banging washing machine with the drums banging the whole time. A technican came out, not only did he put his cellphone and *****driver on the glass top, he proceeded to full and empty the washing machine with water...NO garments inside just water, not once but 3 times. Ended up under the washing machine with a little ***** driver and said it fixed. When we asked what about the leveler he said yes its not working but its not a problem! He also reported back to DEFY that there was no problems!!! Contacted Metro menlyn again and another tech was sent out, he said there is clearly a problem with the machine, not only did he do it correctly by filling the machine with water and garments he also recorded the the noise and banging and to this day it is still making all the washing full of washing powder. He also confirmed that the leverler is broken. People this washing machine was/is BRAND NEW. I want a replacement! I also feel if you buy a item from a shop it is their responsiblility to ensure your issues get sorted. Metro Menlyn you know we have been patient and accomodating but its now been nearly two weeks and we have not heard a word from Metro Menlyn or DEFY! This is really unacceptable! This washing machine was used TWICE and the first tech came out, it was then used only another TWO times when the 2nd tech came out. A BRAND NEW washing machine! It is not right that this is happening and this machine definitely is faulty and no ...... no more so called repairs. Between Metro Home Menlyn and DEFY a new machine needs to be arranged. Very dissappointing and upsetting! Not happy at all
