Washing Machine

My name is Ronica Naidu. I purchase a washing machine from Ok Furniture, I have it for only 1 year and it stopped working. Its a Defy machine. Defy's technician came home 3 times to repair it and he could not repair it. He gave us a job card stating that the machine must be exchanged. 2 weeks ago defy sends some one to pick up the broken machine without delivering the new one, I did not allow them to take the machine because the job card states it must be exchanged. Please assist, in defty's system they say the machine is for pick up but the job card states its for exchange I have the proof. Why are they picking up the machine to repair when their technician could not repair it. They should give me a new machine because the machine is still under guarantee. Customer no: 444195.<br> <br> thank you.
