Getting no where fast with CDA. Long waits on the phone during COVID-19 I can cope with. Polite staff is a bonus but now approaching 6 weeks without an oven because they keep sending wrong parts. I can almost build a new oven with the amount of parts arriving. Not sure why it has been so difficult to send me a main oven fan. One more go getting the correct part (which every time takes 4-5 days to arrive), then I am pushing for a brand new oven!
