6 weeks and counting - still no washing machine repair

On about 19 November our defy washing machine stopped working. A technician was dispatched the next day to come and look as it is still under warranty. The technician identified that there was a component that needed to be ordered. As of today, 5 Jan, we still have no idea what is happening. We have placed numerous calls and get told "the part has been ordered" or "someone will you you back" but no part arrives and no calls are returned. It is starting to cost time and money using the local laundry service to do my washing. Please could someone at Defy reach out and do something as this is now getting a bit ridiculous.
