Defy Washing Machine

Hi all, I have companied since last year October about my washing machine. I rent to own the machine from Teljoy and my last payment was either December or November. We had a guy from Defy who came out looked at the machine and tried to fix it, he said I must let him know after I've used the machine if all is ok, which I did immediately after my first wash. He then said ok he know what is wrong and will order some part that he must replace. After 6 - 7 weeks he rock up at my house looking for the part in the van but could not find it. Then he said he will come as soon as he receive that part. I then waited again for another week or two. He then came to do something but the washing machine is still giving the same problem. I immediately phone him again to tell him we still have the same problem and that was mid March, he said he did ordered and is still waiting. I then phone Teljoy last week again to complain again and I spoke to Boniswa and she said that the manager Randal will contact me that same day. Up to today I AM STILL WAITING ON SOMEONE TO PHONE ME AND THIS IS NOW REALLY GETTING TO ME!!!! PLEASE CAN SOMEONE COME AND SORT MY MACHINE OUT AFTERALL I AM PAYING MAINTANENCE!!!!!!
